It's recording from and old tv tuner card at /dev/video0. I suspect it interact with the video card in some way because trying to play videos on a display other than :0 results in blank video, and I'm pretty sure these old bttv848 based cards did direct transfers to video memory (but not onscreen unless you so choose). Given what you say, my guess is that the card is incompatible with compiz. Regards, Daniel -- And that's my crabbing done for the day.
