[MPlayer-users] NOVIRUS mencoder records stereo, but input is mono

Hello!

I have strange bug in mencoder: I grab video/audio from my tuner in mono
sound (you can see below), but mp3lame records stereo (mplayer -dentify
tv.avi says that, see below). I suppose, that mencoder is wrong
initializing mp3 coder, even if I type options to lame to force mono
sound (mode:3).

I have:
