Install and use the mencoder command almost the same way as for watching
with mplayer. Consult man mplayer for option for both apps.

I've been using following script for analog TV. YOu can modify it or write
your own one

------- script start ------
#!/bin/bash

CH=$1

TV_DRV="driver=v4l2:outfmt=yuy2:width=640:height=480"
TV_NORM="norm=PAL:normid=0:chanlist=europe-west"
TV_DEV="device=/dev/video0:input=0"

now_date=`date '+%Y%m%d-%H%M%S'`
mencoder -tv $TV_DRV:$TV_NORM:channel=$CH:$TV_DEV \
         -ovc lavc -lavcopts
vcodec=mpeg4:vqmin=2:vbitrate=1200:mbd=1:keyint=300 \
         -oac lavc -lavcopts acodec=mp3:abitrate=128 \
         -vf scale,pp=lb,denoise3d -o ${now_date}.avi tv://
------- script end ------
