Actually I do:

mencoder dvb://Telecinco -tv
driver=v4l2:device=/dev/video0:forceaudio:norm=NTSC-M:chanlist=us-cable:alsa:adevice=hw.0,0:immediatemode=0
-ovc xvid -xvidencopts bitrate=800 -oac pcm -endpos 1800 -sws 1 -o
Karlos_Arguiñano_en_tu_cocina.avi > /home/david/messages 2>&1

But 30 minutes are 500 mb!!
