Help with tv tuner setup

[Karolis Tamutis]

The metal boxed part on my card wasnt so informative, nothing about
the tuner. After looking at my card, I can just confirm that it has a
Conexant fusion 878A video capture chip. I've undid all changes to my
kernel config and tried bktrplay again, this time it doesn't exit with
error, just shows a screen with grey video debris (well, you know how
it looks), but thats no mater what video standart or channel I choose,
everytime's the same.
