[MPlayer-users] Trouble with grab tv via mencoder

[yopt]

Hi.

I need to digitize video cassete. I use mencoder for this.
But i have some trouble: 
when i tried digitize tv program I receive something like that:

mencoder -tv
device=/dev/bktr0:driver=bsdbt848:norm=PAL:input=4:chanlist=russia:width=400:height=300
tv:// -ovc lavc -oac lavc -lavcopts

Please supply the text font file (~/.mplayer/subfont.ttf).

Compiler did not align stack variables. Libavcodec has been miscompiled
and may be very slow or crash. This is not a bug in libavcodec,
but in the compiler. Do not report crashes to FFmpeg developers.
