I have been playing with the HD clips from Apple, Nero, and Microsoft, and noticed (escpecially with Quicktime 7) that frams are dropped in the high action/detail segments. I watched the Performance Monitor and only about 70-80% of my CPU is being used. I would like to know where abouts the bottle neck is in my system.

Specs:
Athlon 64 3000+ (1.8Ghz)
1GB memory in Dual Channel mode
PCI Express Geforce 6200 (factory OC'ed)

I haven't tried 1080p HD yet as my LCD is only 1280x1024.

But the frame drops aren't too distracting, as the extra detail is really stunning. (If I have enough money I might get a HD-DVD drive when they come out).

This might be of some interest. I have T2 Extreme edition which has a WMVHD version of the movie on one of the discs. I won't go into the DRM of this disc but I did manage to eventually remove the DRM on the disc (the DRM adds its own overhead). This is a 720p video. I can play this on an Athlon XP 2000+ with 512MB memory and a Nvidia N6200 card using WMP and the video is just barely smooth with the CPU running at about 100%. I am using analogue sound. I suspect if I tried to output Dolby Digital sound the additional CPU requirements would cause the video to be jerky.

As you also noted, the quality is superb - I view this on a 56" JVC D-ILA RP set at 720P resolution and it is a bit tantalising in terms of what we might get one day in terms of HD TV or video

With your machine I would have thought playing the nonDRM clips would have been a breeze.

HD DVD only does 1080i? While BluRay will do 1080p

I doubt most people would see the difference between 1080i and 1080p watching it on their HDTV; you might on a PC monitor because you are really close to it
