X800XT PE problem

I purchsed an X500XT Platinum Edition back in January (2005) for my new
homebuilt PC. For the mostpart, the v/c seems to work properly, however
I've noticed that even though my computer is more than fast enough, I'm
getting "chop" when I try to watch HD video clips in Quicktime format
from the Apple website. The only thing I can figure is that the video
card is having trouble keeping up, any suggestions?

I read that this format is *very* CPU intensive. You can't offload
rendering/decoding on the Gfx card (which you can do with mpg2 and wmv).
No card supports (mpg4) decoding yet.

I think for 1080 line clip (1080p) a P4 3GHz CPU is recommeded, or some
such...correct me if I'm wrong.

Make sure AGP fast writes are enabled. Not sure about QT, but this makes a
huge difference in WMV9 HD.

Are these clips downloaded to your hard drive or streaming over the
Internet? If streaming, is your Internet connection fast enough to do
this? Have you optimized your connection for throughput? Have you tried
increasing the buffering? Checked to make sure that dma is enabled for
your hard drives in the bios and the OS?

Assuming you're running Windows, have you defragged lately? Assuming
Windows again, have you scanned for and cleaned off any viruses,
trojans, adware, spyware, keyboard loggers, Sony < and probably others
installed DRM crap? Have you updated all the applicable drivers?

Are you running other programs in the background, possibly started by
your OS without you knowing about it? Are you really sure you have
enough computer in the first place to get the job done rendering HD
video clips? You give no data.

I'm not rendering anything, just watching HD movie trailers from the
quicktime site. The computer is all new as of January 2005, here are
the basics:

1. AMD Athlon 64 4000+ processor on MSI socket 939 motherboard
2. 1 GB RAM
3. 120 GB Samsung HD
4 ATI/Sapphire Radeon X800XT Platinum Edition video card

AMD rates my processor at 2.4 Ghz, but it benched faster than a
comperable 3.8 Ghz Pentium under testing prior to my purchasing it, so
I'm confident that my processor speed isn't an issue. I'm running
Windows XP Professional Edition and AFAIK it isn't running much of
anything "behind the scenes" other than the AOL startup deal, Windows
Messenger and the Catalyst Control Center for the V/C.

If it's H.264 HiDef movie files then you might find this article
interesting: http://www.theinquirer.net/?article=25057

As has been said already, your graphics card doesn't accelerate HD content
so it's all down to the CPU and what HD resolution you are trying to view.

Not had any issues playing HD trailers myself so far and am using an A64 X2
4400, 2Gb ram and a 7800GT (again no HD acceleration).
