I have a customer who, against my better judgement, runs an ATI All-in-WonderMy All-In-Wonder AGP 128 works fine for TV and Composite/SVGA In. Recording
PCI TV card under Windows, and it works flawlessly using the default ATI
software. Despite my comments about "you are what you see" he consistently
spends 4-6 hours a day watching TV while doing various things in Windows.
He can switch channels, grab picture frames from the TV, and all kinds of (I
suppose) really neat things. Having seen my Mandrake a time or two, and being
passably familiar with RedHat, he now wants to switch from Windows to Linux
for a variety of reasons. Then there is the issue of that blasted TV card,
and almost immediately I hit snags.
Now I have invested over two days researching this matter, both on Mandrake
and in other venues. Has anyone actually gotten a TV card, particularly an
ATI-based card, actually working under Mandrake? Currently I am installing
9.0 but I would change that if someone has actually gotten it to work with
another release.
does not work reliably. Screen captures need to be converted using some
sort of YUV utility which I've never gotten to work. Note: This is
using an older version of the software shipped with Mandrake 8.2 boxed
version.
Glitches: Channel changes cannot keep up with key presses so holding
down a key to switch channels will lead to a few minutes of the
software flipping channels until it catches up with the key presses. In
some color modes there will be visual corruption of some window manager
elements.

Try that script :
#!/bin/sh
case $1 in
1 ) channel=53
chaine=bbc1 ;;
2 ) channel=60
chaine=bbc2 ;;
3 ) channel=55
chaine=itv ;;
4 ) channel=50
chaine=c4 ;;
* ) echo "unknown channel"
exit ;;
esac
echo "Presser "ENTREE" pour d�marrer l'enregistrement de $chaine..."

mencoder -tv on:Driver=v4l:input=0:norm=SECAM:channel=$channel:width=768:height=576 -vop pp=hb/vb/dr/al/lb -oac mp3lame -ovc lavc -lavcopts vcodec=mjpeg -o ${chaine}.avi
Notes :
If you have no sound : think to increase "IGain" value in aumix; this script uses libmp3lib0 to work (in PLF)
You can use frequence value with freq= instead of channel=
You can simply play TV with that command too :
mplayer -tv on:Driver=v4l:input=0:norm=SECAM:freq=$1:width=768:height=576 -vo sdl -ao sdl -vop pp=hb/vb/dr/al/lb
Read man mplayer for other options
