Xgl/compiz and tv card

Hi, Recently installed Suse 10.1 + Xgl + compiz on an ati radeon 9600pro display. Everything is fine, but I can't use my tv card. Do I have to change any setting on xorg.conf? I know Xgl is based on opengl, and tvtime uses Xv driver, so perhaps I have to stick to xv driver?? Thanks in advance...
