So far I'm only concentrating on the video, when I've completed the raw capture of a film with all the English titles restored etc. & side changes added in then I'll capture the definitive LD of the film to nab the audio from, the 28min test clip I did with ROTJ I used audio from Dr_Gonzo's and synched that up, I found that Dr_Gonzo's was 6 frames short for that 28min clip so had to scan through & double some frames to get things in sync.
I'm thinking of producing an NTSC set too, shouldn't be any trouble at all because once I've got a final raw capture of a film I can just alter the VirtualDub filters slightly to spit out an anamorphic NTSC picture instead of anamorphic PAL, plus it'll be just as clean because before the final resize the image is 1280x544 res.
