HD-DVD Playback - On the Xbox 360 & on NVIDIA GPUs

Final Words
From what we are seeing, there are many more stressful H.264 movies currently available on Blu-ray than HD-DVD. The VC-1 titles are definitely less of a problem for modern hardware, but it wouldn't be a good idea to build a system for playing video without building for the worst case scenario.
While H.264 under The Interpreter did provide a good amount of CPU utilization, there just weren't any huge bitrate scenes to test worst case scenarios. As more action packed and intricate movies are released on HD-DVD with H.264, we would be willing to bet that HD-DVD movies could be as stressful as X-Men III.
Right now the format with the highest potential for pushing hardware beyond its limits is Blu-ray. With 50GB disks possible today, we could see 2+ hour movies with sustained bitrates of 45 Mbps under H.264 which would really push even an X6800 system with an 8800 GTX running the display. Of course, bitrates that high aren't really necessary most of the time, so it won't likely be an issue. But HD-DVD is currently limited to 30GB disks which decreases the potential for high bitrate video (which translates to large file size).
Generally, graphics hardware performed as expected based on our previous testing. It would have been nice to test ATI hardware as well, and we will test it as soon as Cyberlink or Intervideo can get us a player that is up to the task.
As far as the Xbox 360 drive goes, it makes an excellent addition for those interested in HD-DVD playback on a PC. The price is right, it's easy to use and set up, and it won't take up room inside a crowded case. It may be a good idea for most people to wait until the dust settles before throwing their lot in with either HD-DVD or Blu-ray, as the market doesn't seem robust enough to handle two competing formats. On the other hand, those who don't mind potentially purchasing dead-end hardware take a much smaller risk by spending $200 on the XBox 360 HD-DVD drive. Getting a Blu-ray player right now is a much more expensive proposition. typically running over $500 (though with the ability to record as well as play back content).
Those who don't want to take a chance on their PC being able to play HD-DVDs can at least rely on their Xbox 360 for that. The drive combined with the remote provided a very simple and easy to use experience. The Xbox 360 handled playing back HD-DVD movies as well as any consumer electronics device could be expected. Of course at a price of around $200 you can't find standalone HD-DVD players for less money, so if you have a 360 or PC that you'd like to use for HD-DVD playback you can get both for less than a set-top player.

Im definitely looking for the data side.You mean the bit rates for H.264 are not 'standardized' yet ?!!
Consider this:
A medium .. The CD .
If I play Led Zepelin compared to Vivaldi . Led Zepelin is going to run my batteries out. ...
BlueRay,HD...
If I buy a high bitrate H.264 I will also need two extra Energizers to power the disk.(Or Duracell ,..put 'your brand here ______)
and
I work at a firm,and my boss cant figure out the reason everybodies notebook battery has gone south. He just knows that the CAD work is completed. Although it had been finished nearly a week ago . And only the BR,HD disks are evidence of it.
I create a BR,HD disk from scratch on a writer.And send them to the relatives.They write back,and uncoincedently to your notice 'each of them ,replacing the batteries after watching them.
Broadcast Radio HD...
40,000 watts in any other format of broadcast .Equals 40,000 watts. 40,000 watts in H.264 eqauls a power outage in 6 broadcast areas.

the mediums (HDDVD(-video or whatever) and BRD(-video or whatever)) have standards for bitrates, however, (AFAIK) .. i WISH i knew them, but i don't. DVD(-video)'s theoretical limit for continuous transfer is around 9.8mbit (i've heard of mastering houses having encoders that can peak over 12-15+ mbit for the video alone in a really small timeframe), but replication houses will reject anything substantially over 8mbit.JarredWalton - Sunday, December 17, 2006 - link
Actually, MPEG-2 and MPEG4 level 10 (H.264) all have various options available. Ever wonder how a program can "shrink" a 9GB dual layer DVD to fit on a 4.5 GB single layer DVD... and yet that DVD is still playable on any DVD box? H.264 is a standard, and if a device fully supports the standard you can play any H.264 content. Here, though, we have a problem where a higher bitrate H.264 disc will require more computational power to play.As far as laptops and battery life go, I'd be surprised if anything currently available will get more than two hours of BRD/HDDVD playback off a battery. Of course, if you're just watching a movie on your laptop, the difference between DVD and BRD/HDDVD isn't going to be *amazing* (despite what the marketing might say). Better, yes, but if you demand more battery life you'll probably want to stick with DVDs for a while.

I would have thought the difference in quality would be more noticeable in laptops than most other places as many laptops have high screen resolutions - my 15.4 and 17 inch laptop screens are both 1920x1200 and with certain DVDs look quite poor as there's so much upscaling compared to lower resolution screens which seem ok with DVDs.I agree on batterylife though, while watchiing DVDs I normally have the CPU and GPU on their lowest power mode whereas HD DVD/BR is going to need everything running full pelt which is likely to tear through the battery a lot faster.

Seriously guys, at least a blurb in there would have been nice. I understand that this is just an overview of HD-DVD/BD performance, mainly for GPU buyers. But in this particular case I need to know if I'm wasting my money if I buy something like a 7900GS vs a X1900GT/X1950Pro. Judging by your BD article, my X2 3800 @ 2.5ghz wouldn't work very well with the ATI cards.Your reviews usually make it impossible for us to NOT make an informed decision. Now it seems to be the opposite.

I believe Derek mentioned that we will include a CPU comparison in our next major CPU review. I'm currently working on Part 2 of our AMD Brisbane coverage, but after that I should have some time to work on a comparison of BD/HD-DVD decode on modern day CPUs. The only issue with doing a CPU comparison is that the only metric we've really got to compare with is CPU utilization, which only tells us what's playable and what isn't, not which CPUs are going to be better at decoding H.264/VC1/MPEG-2. Regardless, ask and you shall receive, it'll be next on my to-do list right after Brisbane part 2 :)Don't be too hard on Derek, I don't let him near my CPUs. Those GPU guys always rob me of my fastest test parts ;)
Take care,
Anand

Thanks very much Anand and the team, for all your excellent reviews and technical info. I love this site.This decoding stuff is pretty interesting, that faster GPUs actually decrease CPU utilization. I guess that means the GPU is doing as much processing as it can.

Thanks for the quick reply, I definitely understand that the CPUs would be more difficult to compare than the GPUs. You guys are a firefox homepage tab for me, I'll keep checking back religiously as always :)BeefyB - Friday, December 15, 2006 - link
The review is using beta software, can anybody else actually get this? I've been looking around and the best currently available software that I could see is that a person can buy the japanese version of windvd. If the hd dvd software is available, can somebody point us to it? If it isn't available, it seems like a worthwhile thing to mention in the review.DigitalFreak - Friday, December 15, 2006 - link
Supposedly the retail version of PowerDVD that plays HD-DVD & Blu-ray will be out this month.
