Bug description:
=======
Videos tear when I play them with xv extension. I enabled vsync with Catalyst Control Center and running 'aticonfig --initial --input=
I have this problem since Hardy with a Radeon HD 3650. Even Windows XP with Catalyst driver tears. Some time ago I switched to a Radeon HD 4670 (see lspci-vvnn.log), but even this card tears.
The videos tear and do not flicker. This bug also occurs with Compiz disabled.

It seems to be a general FGLRX problem. I can confirm this with Ati 4870. The only workaround so far is to enable vsync in the Control Center and use the OpenGL video output. But the OpenGL output is far from perfect too.
