TTL RGB ==> PC

Hiya, I think I've tried three different BT878-based TV cards in Linux - I've only ever got one of them to semi-work (despite them working in Windows - albeit at awful quality and in a tiny little window on the desktop that makes them next to useless anyway). That's against a TV signal too - I've heard from several sources that TV cards have a real problem with the modulators used in typical 8-bit micros (UM1233 etc.) The Linux code for TV cards seems to be something on an undocumented mess :-( It seems like a lot of unnecessary complexity to go TTL->composite->RF and then back to digital again, too. No, I don't need a PC. I just need *something* in the US that can cope with typical UK-style picture formats (typically 'home' micros in the UK will be designed around PAL signals at 625 lines interlaced I expect, whereas I expect US micros of the 80s were geared more toward NTSC displays of 525 lines) I'm not sure if VGA will cope either - I don't think a typical VGA monitor will sync down to the frequencies involved (i.e. converting TTL to the necessary 'analogue' RGB of VGA is the easy bit :-) Oh, sync lines on the machines I've got are typically composite, so some sort of sync separator would be needed too... This just strikes me as the sort of project that people will have done before, because monitors take up lots of space and because there's not a lot of sense in going from a digital source to analogue and then back to digital again. cheers Jules
