My limited experience is that the picture comes up every time, but,
there is a delay while it locks in to the station. The only real
problem I have is that sometimes there is no sound until I switch tracks
(numpad +/-). A few other people in Australia have mentioned similar
issues, and I think it's to do with the AC-3 sound.
I haven't tried the very latest drivers from linuxtv.org. I tend to
wait until they come out in an rpm.
