Also the addon isnt a standard optical HD DVD drive.
On the current PC drives, alot of the processing is done before the stream is sent to the PC for display. All the PC does is have software or hardware that can decrypt the stream and display it, the PC does little to "no" processing of the video itself.
The add-on will require the PC to do all the processing of the video and the Xbox360 proves that to be a demanding task.
If they ever do crack the add-on drivers, dont expect to be able to use this on any normal PC, you will probably need to have a Dual core at the very least.

Are you saying you can decode 4 H.264 encoded videos at the same time? Prove it, because i know you cant.
Same goes for 1080p, you arent decoding the data from a HD DVD disk. You are decoding what someone else has taken from a rip of a HD DVD or a video thats designed for the internet.
You have absolutely no idea what you are talking about since you dont have a HD DVD drive.
Go download a true HD DVD rip of a 1080p movie, it will be well over 10GB.
My AMD3200+ i have in the living room can handle 2 720p videos to play on my projector, my AMD 64 X2 4800+ can handle 4 720p videos at the same time easily. But fact being, im decoding videos i downloaded off the internet that are using less stressful compressions.
Get your facts straight before you talk.

On the current PC drives, NONE of the processing is done before the stream is sent to the PC. The HDDVD drives that Toshiba use in their Laptop drives today are just standard HDDVD readers - the Laptop does ALL of the decoding, processing, and display. Some of this is handled in the video card, and some in the CPU. Just like the XBox360, the PC does ALL the processing.
You can ALREADY use this drive on a "normal PC" - using Toshiba's HDDVD Drivers for Windows XP, and Intervideo's WinDVD 8 to play the movie, it works. It certainly is a demanding task, and required a reasonable PC.

mcc, PureVideo is certainly an excellent solution. I use it myself for 1080p H.264 footage as above - it shifts a lot of load from the CPU to the graphics card hardware (a 7900GT in my case). The more decoding you can do in graphics hardware, the less your CPU is left to do. I've found I get about 90% CPU use without PureVideo.
Vietone, OH DEAR. Again, you're completely wrong. Who is the idiot now exactly ? Why resort to insults ? I suggest you go and do some research before you post any more of your drivel.
I personally DO decode the H.264 format that HD-DVD uses, in 1080p. Whether that data is coming from my Hard Drive or an HDDVD is completely irrelevent - it's the exact same stream for the PC to show. You obviously haven't seen Toshiba's HDDVD laptops - they're on sale right now, and also play HDDVDs. You really should "get your facts straight before you talk".
My true HDDVD rips of 1080P movies ARE well over 10GB (infact they're closer to 30GB) - what does this have to do with anything ?
Why do you think changing the source of the video from HDDVD to internet/harddrive has any effect ? Do you think the 1s and 0s making up the stream, are different when they're being read from an Optical Disc ?!?!
A reasonable PC has no trouble whatsoever decoding an HDDVD-bitrate H.264 at 1080p.
If you don't believe me, then try it yourself, right now, with WinDVD and an XBox 360 drive.

Ita makes a world of difference.
If you were to rip the movie from the HD DVD, it will no longer be recognized by Nvidia PureVideo or ATIs Avivio unless you re-encode it.
When playing from a HD DVD it streams to the computer, the Nvidia PureVideo and ATi Avivo software has to be installed, and a compatable player has to be installed to use the PureVideo or Avivo features, and the stream from the HD DVD has to be within spec to be decoded by PureVideo or Avivo.
When you download a movie from the internet that says HD DVD rip. Its re-encoded, then placed into a container. Thats why you need a media splitter like Haali to play the file back, because it separates the streams thats in the conatiner file, and therefore is not recognized by PureVideo or Avivo.
For PureVideo or Avivo to work, it all depends on where the source is comming from.
From the internet, you always use your own processor to decode, from HD DVD or Blu-ray disk's, its always from processor unless you have Purevideo or Avivo installed.
Get your facts straight.

> Nvidia PureVideo or ATIs Avivio unless you re-encode it.
That's not true. Providing you encapsulate your rip as an AVI file (or something else you can play within Windows Media Player or similar), then PureVideo will step in and decode it. It's the H.264 stream that activates PureVideo - it doesn't matter where that stream is coming from. Try it yourself !
Alternatively, you can make your own AVI file if you like from another source, using the exact same codecs and bitrates as an HDDVD, and you'll find that it plays just great in Windows Media Player via PureVideo.

No - it depends on the format and encoding of the source. Again, try it yourself ! PureVideo steps in to decode quite a few formats within Windows Media Player.

No. Again, try it yourself ! PureVideo doesn't care whether you're playing from an HDDVD source or not - it happily decodes AVIs and MPEG2s and TS streams, and even normal DVDs !
I note that you have backtracked on your original stance of "this doesn't work" ! I hope I've convinced you that it's perfectly possible to play 1080p video on a PC, encoded with H.264, at the same bitrates as an HDDVD. You can buy a Toshiba Laptop *right now* with an inbuilt HDDVD drive and WinDVD 8 pre-installed, which will play HDDVD movies out of the box. It's trivial to duplicate this setup on any decent PC.
