[mythtv-users] Aspect ratio problem due to fglrx ATI Driver ?

[Rayene Ben Rayana]

Thank you Paul,

I disabled the "DRI" Module and the "Radeon" driver works perfectly now (2
days without a crash :) ) ! All aspect ratio are operating as they should.
I spent several weeks asking people on formus why the "Radeon" driver was
hard crashing my computer and nobody could help me !

Thanks again,

Rayene,
