Xvideo broken with 100.14.19
1 Attachment(s)

recently switched from 9755 to 100.14.19 for better suspend support (sidenote: would have preferred 100.14.11 due to bug reports here but that version doesn't compile with kernel

Unfortunately, Xvideo regularly goes bad when watching tv with xawtv, especially when doing stuff which might involve some screen action, like starting gimp or restarting my window manager fluxbox. All I then get in xawtv is a static, garbled screen, and dmesg spits out two of those infamous Xid lines:

NVRM: Xid (0001:00): 8, Channel 00000000
NVRM: Xid (0001:00): 30, L1 -> L0

No problems with 9755 though (apart from broken suspend, of course). Log attached.

EDIT #1: for other casual visitors of this forum, found the patch to get 100.14.11 compiling on 2.6.23. See

Re: Xvideo broken with 100.14.19
This is a known issue that should be resolved in the next driver release.

Re: Xvideo broken with 100.14.19
Thanks for the info. I don't quite dare to ask, but is there a public place where known issues (and maybe known patches) are kept track of, like a public bug tracker or something? Or put differently, how do *I* come to know what is known or not?

I'm the kind of guy who usually updates his driver at most once a year, and when I do I want the best compromise between recency and stability. Finding this optimal driver version usually takes quite some time, normally including several cycles of running into "known issues", searching through this board for them and downgrading to a former version.

Even just a sticky post here briefly listing known issues for various versions as they come up would be a great help in reducing the amount of that - essentially wasted - time.

One workaround you may want to try is to see if your application supports OpenGL rendering. (mplayer, xine, and MAME all support a GL alternative to xvideo rendering) In my experience you can get better quality that way too.

Re: Xvideo broken with 100.14.19
Thanks, I already helped myself out with mplayer until I found time to install 100.14.11. Point is that mplayer (and those other apps you mentioned) eat considerable processing time when compared to xawtv, which really is very light on the CPU (and likely on the GPU either). The same applies e.g. to tvtime with all it's fancy filtering, so for me xawtv is really the best choice.
