VUDU's Re-Do: The Bandwidth Burden's On You

Speaking of Internet video distribution...when I last mentioned VUDU, a longstanding focus area here at Brian's Brian, the company had just laid off 20% of its staff and had added porn to its content repertoire. One month later, what's changed? Encouraging developments, at least at first glance. The company's bundling $200 in free movie credits with each box sold at Best Buy. It's also now offering high bitrate 'HDX' versions of its high-definition titles, at no incremental rental cost to conventional high-def counterparts.

Given my past criticism of VUDU's high-def video quality, you might think I'd be thrilled with the news. And I was...until I took a closer look. As the below screenshot shows, the HDX version of a title takes substantially longer to download than its conventional HD counterpart:

When I first heard about VUDU's no-added-cost HDX plans, I was therefore initially confused; wouldn't the incremental storage and delivery bandwidth incurred by the company unduly eat into its profit? But then I recalled that VUDU relied on a P2P model for content distribution...and the light bulb went on in my head.

My VUDU box is (or more accurately was...keep reading...) router-tethered via a HomePlug AV powerline spur, so it's pretty easy for me to monitor its network access patterns by viewing the activity lights on the corresponding Actiontec HPE200AV adapter. About a week before VUDU launched HDX (and in preparation for the launch to come, I now realize), I noticed that the VUDU box (which had already monopolized my DSL connection much more than I preferred) was constantly doing data transfers. By constantly, I mean 24 hours a day, seven days a week. Ever since then, my VoIP sessions have suffered from frequent dropouts, 'ack' responses to 'pings' I make to various servers have been substantially delayed, and network clients have generally suffered from degraded LAN and WAN performance.

Last Sunday, I finally had enough. I powered down the VUDU box, and network performance returned to normal. I'm keeping it that way; as far as I'm concerned, VUDU will never again dominate any network I'm responsible for. You're therefore going to have to take David Pogue's word on HDX's claimed 'insane sharpness', because you'll get no quality review from me. Anyway, I'm skeptical that HDX's incremental image improvement will lead to success with mainstream consumers. A big part of the appeal of Internet-delivered video is the instant-gratification factor...instead of getting in your car, driving to the video store, finding out that the movie you want isn't available and settling for a less appealing alternative, then driving home, you can punch a few buttons on a remote control and, within a minute or few, be enjoying the exact title you want to watch.

Now consider the HDX scenario. 11+ hours is by no means instant gratification. In fact, it far exceeds the roundtrip video store alternative. Granted, I realize that you can queue up a download in the morning, either from the box or online via account access, and it'll be ready to go that evening...but where's the spontaneity in that? And will the average consumer notice the claimed quality improvement, anyway? It's a funny thing about video compression, which I've seen time and time again in my own testing; up to a certain point, increasing the compressed bitrate makes substantive improvements in the quality results but, past that codec-, setting- and content-dependent threshold, the return on the incremental bitrate investment rapidly disappears.

Here's my theory, and it's at the root of my disappointment with VUDU's continued P2P reliance. I suspect that the company has given up on capturing a sustainable beachhead versus bigger online distribution competitors such as Amazon, Apple and Netflix. Instead, it's (in true dot-com tradition) throwing out any pretense of securing a profit, in favor of garnering as large a customer base as possible as quickly as possible, and in the hopes of finding a bigger-pocketed buyer. It's burning through its accumulated hardware inventory via a Best Buy fire sale. And it's making its loyal early adopter customers shoulder the incremental bandwidth burden, caps and throttles be damned.

I'm not remotely impressed. Shame on you, VUDU.

Brian, have you seen any HDX movie yet? If you have only 2Mbps then you can only watch hulu or youtube or SD without impacting your VoIP. If you want to have high quality video and you want the stream to have low bandwidth usage, fast download time, then you are asking nonsense. It''s not realistic at the current technology and network infrastructure. I am disappointed with this writing, really disappointed!

This is why physical discs, such as Blu-Ray are not dead. With Blu-Ray, you have the highest-quality image and sound and no downloading. Brian is lucky to have the DSL he has. Many people, like my parents, live further away from a city and their best network speeds come from satellite internet, with speeds much slower than 1 Mbps (advertised to be about 1 Mbps) and long latencies. I happen to have fiber-to-the-house from SureWest, so VUDU's service may work well for me, but I can understand why it isn't for everyone.

@"VOD download" - You've completely failed to see the authors (extremely valid IMO) point regarding Vudu's bandwidth usage. Of course we all know the limitations of bandwidth, and it would be unfair to blame a movie download service for the limitations of our connections. If you pay a little more attention to what he's saying I'm sure you'll appreciate the issue. The issue ISN'T simply download bandwidth - even if you've only got a 2-4MB connection, at least if Vudu uses all your bandwidth to serve you a movie, you know it's for YOUR benefit. Vudu's use of YOUR bandwidth for IT'S benefit is a completly different matter. As I've also found to my cost the big issue with Vudu (and AFAIK this is unique to their service) is the P2P aspect which means the customer UPLOADS the movie data to other customers on Vudu's behalf. A fact they don't exactly go out of their way to broadcast. I was able to monitor this activity on my network and see that not only did my Vudu constantly upload data, taking around 40-50% of my available bandwidth, it also downloaded large amounts when not in use, leading me to believe that it downloads and caches movies I haven't ordered and serves them to others. On my 20mb/sec downstream, 768kb/sec upstream (if I'm lucky) cable I could quite comfortably download a 10mb/sec (Vudu's claimed average data rate for HDX) film directly from a movie download service capable of providing it at that speed, leaving me plenty of headroom to do other things on my connection. With Vudu on my LAN I've got so little upstream bandwidth left that it severly impacts on the useability of my network. I wouldn't mind if it was for MY benefit, but it's not. Not only that, if I had a capped or pay-by-use connection it would actually cost ME money to subsidize Vudu's movie distribution. Not on, not on at all.

Dear Ray Von, I haven't rented a movie in several weeks, yet VUDU still uses substantial amounts of both my upstream and downstream bandwidth. So although I realize that some of that download payload is caused by them 'pushing' me previews, the first few minutes' worth of each film for instant-on standard def purposes (as I've written about at www.edn.com/blog/400000040/post/1000026300.html), etc, I concur with you that VUDU is likely also using my box as a server housing substantial amounts of content that I haven't even asked for. Thanks for writing

@"Ray Von" - First: I disappointed with Brian since if he was talking about HDX then he could consider to talk about the quality of the movie. If he just used that to criticize about bandwidth usage (regarding 11 hrs download) then it's nothing new. It's just repetitive info over and over from his previous articles. Only advertisement or negative campaign does that. - Second: there is option to lower the bandwidth usage to suite the user limit. If the user lowers it down to "Delayed SD" then it use the max of 100 kpps to upload. A lot of Comcast/cable modem got built-in UDP flood protection, and it caused the network slow down. - Third: P2P is the only technology that can allow you to have HDX (closest download quality) with the same price of HD. It's sharing and utilize network when idle.

@Brian, Your experiences with Vudu as regards bandwidth usage do seem to closely match my own. Their support personnel are reluctnant to talk about the "nuts and bolts" of their P2P system, and I was told the same story that it was likely just previews and intros when I enquired why it was using so much bandwidth when idle. Whilst I do think the service has several good features, it''s the fact that I can''t just get a movie from it, I have to commit to distributing that movie on their behalf too, sticks in my craw somewhat. Perhaps I''d be less annoyed if their movies were cheaper than other services. Regards, Ray Von

@"Ray Von" - It's cheaper if you consider it offers more than double amount of data/bit rate in HDX for the same money. It's like 50% off. For the lower end, VUDU got .99 list (not just the library filer movies).

@"VOD download" I''d say an up to 11 hour delay between purchasing and watching a movie was obviously relevant in a discussion about a service which trades on it''s convenience, so I''m a little confused why you''d feel that it should be swept under the carpet. It''s especially relevent with the advent of Vudu''s HDX, since they''ve effectively just increased the size of their titles. If HDX becomes popular, they''ll either need to increase the size of their P2P base accordingly, or increase the amount of upload each existing peer sends from it''s current maximum of 300KB/sec. The alternative is to face the prospect of their P2P network grinding to a halt. It''ll be interesting to see what happens. Thanks for the advice, but I''m already aware of the "Nice to network" options on the Vudu box, I''ve also tried QoS and bandwidth management on my router to control traffic. Unfortunately as you say, Vudu is designed so that the service degrades if attempts are made to limit the bandwidth available to it. I''m not with Comcast, and I know precisely what the overhead of the Vudu box is. As to your final statement regarding P2P, there are plenty of places where you can download files (which is all movies are) at much higher rates than Vudu''s HDX average of ~10mb/sec from a single server, without using P2P. The downside is that all that bandwidth costs money, which is why Vudu is getting their customers to do their distribution for them. Regards, Ray Von

What kind of Crappy DSL connection do you have? THe HDX movies on took 3 hrs on my Comcast cable connection.

Whoopy-fecking-do for you. Did you even read the article? Its about >UPLOAD< bandwidth dummy.

Brian-- All you ever do when writing about Vudu is bite, bite and bite. I am not sure why you hate this startup and its product so very much, but your reactions seem a bit exagerated to me. I bought a Vudu box early on, and I simply love it. My Internet connection has not flinched after installing the box, and I did not notice a slow down since the HDX addition. The standard HD quality it offers is enough for me anyway, and as far as I am concerned, Vudu is the best set-top box available out there. I hope they make it throught these economic tought times and keep adding to their impressing movie collection.

Having owned VUDU since March of 2008 I am not very impressed. The movies you want to see are for sale only many times and the cost to download HD or HDX movies far exceeds the cost of NetFlix Bluray rentals. The final problem just arose We have a 6000 kbps download/256 upload connection.The service was seriously degrading over the past month. We called in a tech and he traced it to the VUDU using up a tremendous amount of bandwidth, in fact a call to the provider said our usage went up 10 fold over the past month, our computer usage was normal during the period and we haven''t downloaded any VUDU movies for at at least two months. I would stay away from VUDU. The P2P bandwidth sharing is really sleazy. I have unplugged my VUDU...What a waste of money.
