KWin compositing effects are switched on by default in KDE 4.2. Did you switch them off? (System Settings->Desktop->Desktop Effects)
Yes, all desktop effects are disabled, as I see no need for them.
With desktop effect enabled the problem is a horrible video flicker, but as I said before, I have no compositing window manager enabled, and the problem is a hard lock while playing a video.
I tried with opengl (textured) video and overlay, and both cause a lockup.

Try turning textured video off. I have the same problems and turning textured video off has solved it for me. I also had this with the previous 9.1 catalyst version.
1. "Desktop Effects" normally require a compositing window manager, and enable compositing automatically when you enable desktop effects. There may be exceptions to this, of course.
2. AFAIK you can't really turn TexturedVideo off for 5xx and higher GPUs, since they don't have the same video processing hardware in the overlay block.
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 :
TexturedVideo on
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 (??)
