I'm blogging my process for making PAL to NTSC DVD's and hopefully vice versa. Got some movies that won't play on my DVD player because they came from England.
We will work this out step by step!
What I heard from my friend K. is that to copy a DVD and make any changes to it you have to de-crypt it first with a ripper program. Then convert the decrypted VOB files to Quicktime or AVI (that's windows' video format) and then encode a new Mpeg-2 file, then burn a new disk. So you have to have a DVD burner program at at least and a DVD burner.
I've tried ripping before but it's been a while. Never tried converting formats though or re-editing the movie. Well I have a VOB file that K. gave me that is already decrypted to try some fun things.
Going to try something later today.
