Forgot to ask: are talking about digital or analog channels?

I've tried tvtime, but I couldn't catch any digital channel (maybe I'm missing something - never used tvtime before). However, mplayer works fine with both analog/digital. Have you tried mplayer?

I don't have much time to investigate until weekend, will report back later.
