I tried setting norm, card, tuner in the kernel and although that does show the right card/tuner in dmesg when running kbtv it never seems to tune or anything (fxtv likewise). So it looked better but didn't help.. On Monday 27 February 2006 21:50, Danny Pansters wrote: > Hi > > I'm having issues with a WinTV card on 6.1-BETA2.
