OK, I tried changing it and rebuilding. It didn't fix it. The WinXP driver doesn't have any problems, though. I can send you some video,
XP might use some "Direct Draw" YUV-Blit stuff instead of the video overlay.
but files are very large(285MB) for just a couple of minutes.

I noticed that the other night as I was working on the driver, but I didn't have any content large enough to test it with. I think it might be a hold over from the old r128 driver. switch it to 2048x2048 and give it a shot. It shouldn't hurt anything. If it works we can submit a patch to get it fixed in future releases.

Hello.
I have a HD-2000 HDTV PCI card. When using the XVideo extension to
display HDTV format video, the right third of the image is a pink
bar.
This looks very much like the overlay simply isn't capable of that size. Especially if the pitch is OK (read: the remaining contents of the video is displayed in order). It could very well be that the overlay can only deal with videos <= 1280 in horizontal size.
I don't know anything about radeon hardware, but on some other hardware, there sometimes exists a register for the line buffer length (or FIFO size or the like). Perhaps such a thing exists on the radeon, and needs adjustment for larger videos.
Other issues that usually influence the overlay capabilities are dot clock and display resolution. However, in such cases, overlays mostly show a different effect, like flashing dots, rather than missing areas.
>>I have looked through the driver source and noticed that
although the maximum image size in radeon_video.c is 2048x2048 , the offscreen image
size is limited to 1024x1024. Is this likely the cause of the problem? If so, will it cause problems if I change it to 2048x2048? I have a Radeon 9000 with 64MB ram, and am running X at 1152x864 @ 75HZ.
