I will have to fix this, it should use the video groups adev and not MPLAYER_AO_DEV. Because mplayer has different options depending on the mrl.

Talking out of my hat, your correct is should be 'alsa:adevice=hw.1,0' I have a pinnacle 110i card which is a saa7134 based card so I can test the results. the command line: mplayer tv:// -tv driver=v4l2:freq=211.000:device=/dev/video2:alsa:\ adevice=hw.1,0:amode=1:audiorate=32000:forceaudio:volume=100:immediatemode=0:norm=PAL worked just fine. > >> In addition, should the adevice part be the same for both mplayer and >> mencoder?
