Hi again, I'm in the UK too, so hopefully will be a similar card (is it a 990 model or the newer 992?)
When I used the svid connection, input 6 was the correct one (4 is the tuner, 0 the composite which I use now) Therefore # /usr/bin/ivtvctl -p 6 # dd if=/dev/video0 of=/dev/video16 bs=64k (btw did you try all 9 inputs on the card? you should get static on 4, and prob a b+w image on 0) Could you send the ivtv init output from your /var/log/messages file which I can have a check through later. Should be obvious if the card's properly recognised and setup etc. [might as well attach your modprobe.conf as well] Which version of the ivtv driver and firmware are you using - is this from atrpms or have you compiled it yourself? Because you can see the test image from the card on the TV, I'd assume the cable was fine (is it a switchable SCART or clearly marked for directionality?). I remember the test_image bit would cause my card to never get back to a clear framebuffer and needed a cold restart to clear. As you know if works, I'd refrain from doing it during testing again to eliminate potential probs it causes. It's good news that catting video0 to a file and playing back gives a perfect video though... Was this input 6?
