Sample mplayer command line that will play TV for Europe, channel E2:
mplayer tv:// -tv driver=v4l2:norm=PAL:input=0:amode=1:width=384:height=288:outfmt=yv12:device=/dev/video0:chanlist=europe-west:channel=E2
Hi Egil - nice line; I copied it to TV_Viewing since only your profile links to this page. Feel free to reorganize the TV Viewing page, perhaps making mplayer its own section if you want to add commands.
Cheers, Dave (please remove this comment when you've seen it)
