I've had good results with this line:

mencoder tv:// -tv
driver=v4l2:width=768:height=576:norm=pal:input=1:alsa:adevice=hw.1,0
-oac lavc -ovc lavc -lavcopts
vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=15:acodec=ac3:abitrate=192:aspect=4/3 -of mpeg -mpegopts format=dvd -vf scale=720:657,harddup -srate 48000 -af lavcresample=48000 -ofps 25 -o test.mpeg

This gives you a video stream that's ready to be put on a (PAL) DVD.
Note I'm using an external USB TV turner, so you'll have to make sure
your device names are correct for your setup.

hope this helps
