--- Comment #6 from Mojo mojoman69@gmail.com 2007-12-02 19:26:56 --- I am using a Nvidia GEforce 6800LE with the latest drivers in ubuntu gutsy repos ( nvidia-glx-new 100.14.23+2.6.22-13 ) X has twinview+xinerama, nothing has changed from 2007-11-06 in my xorg.conf. 2007-11-06 was the last build I have without this bug.
I also CP'd the source over to my debian/lenny laptop and built a deb package on that machine with the same results. That machine is using an ATI 200M Express vid card.
I did find a slight workaround... if you have a video playing when you start a application with wine you can stop / shutdown/ and restart videos without a problem. if you have a video PAUSED while you start a wine app it seems to be about 50% that the video will restart correctly, if it does restart correctly XVideo acceleration will continue to work. If the paused video is corrupted when you resume playback then XV acceleration will not come back until after wine gracefully exits.
if it would help my sources are separate, i could diff them and post the differences between 2007-11-06 and 2007-12-01
