except if someone knows how to grab video from 31Khz+ signals
There are down scanners that let you hook 31Khz signals to TV's. I also wonder if these HD tv's with VGA inputs output the video on scart so they could be recorded that way? (Direct to DVD Mmmm)
As for if anyone has hardware, I have a PPC Miggy and a Vlab card (not in the miggy at the moment though) but I havent used it for long (I couldnt capture the video at anything above about 3fps :-/) so sorry cant help.
