1. I have no good suggestions about automatic IVTC methods or IVTC of any kind.
3. I don't have any idea of where to find such a thing in the first place. I can only access the internet at work so any sort of P2P or Torrent thing is not going to happen in any way, shape, or form. Again you are on your own.
5. As far as doing subtitles for a DVD...You couldn't pay me enough to do that. It takes up way too much damn time. It's much easier to pay a person 300 bux and have them give you a text file with all that info instead of sitting around doing it yourself.
FREE YOU SAY! NO WAY MAN!
Good luck anyway.
