For a few days I thought the driver was not working but I ended up using mencoder successfully with the following line: mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd:tsaf -vf scale=720:576,harddup -srate 48000 -af lavcresample=48000 -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=8000:keyint=15:vstrict=0:acodec=ac3:abitrate=192:aspect=4/3 -ofps 25 -o johntest1.mpg tv:// -tv input=1:norm=PAL-BG:amode=1:alsa=1:adevice=hw.2,0:forceaudio:immediatemode=0:volume=100 I was using Ubuntu 12.04 64bit, 3.2.0 kernel. Hopefully this will give you the clues to get mplayer to work, I was never able to get VLC to switch to the correct audio input although video worked ok.
