Hi,
I've just replaced my Pinaccle card with a SAA7130 card. The system has
recognised the card, but tvtime is giving absolutely nothing out -just a
black screen.
When I right click to set things up, I get a video card called "default"
but am unable to do a channel scan or anything like that.
dmesg comes up with

Any help on setting this up would help! I am not sure if the above is a
tvtime problem or a kernel problem.
