I have the following GPU: RV350 AR [Radeon 9600] rev 0.
I am sorry for my bad reply but I did not know that texturedvideo for newer ATI graphic boards can't be turned off.
Altough I do know that my graphic board has hard coded overlay support, I experimented with the texturedvideo parameter to see if it enabled me to play xv video using a composite window manager desktop. And it actually did gave me some positive results although the video was flickering.
Since 9.1 I am forced to turn it off because when I use totem movie player to play a video with texturedvideo = on, the screen turns black and the system locks up.
Desktop effect are disabled, I disable them as I find them annoying.
In Kaffeine (whick uses xine backend) the only video output options that work are xv and xshm, and both cause lockups. As i understand, textured video work only with opengl output, right? So textured video is not causing the lockups.
glock24; textured video uses the 3D engine but does not use OpenGL. For your system the normal settings would be :
VideoOverlay off (5xx and higher don't have a video processor in the overlay block)
OpenGLOverlay off (this is for workstation apps which float another layer of graphics over the work area)
It sounds like the common thread here is some hanging during textured video playback (??)
