A friend of mine just reminded me of what happened once when we tried to burn a copy of the disc she'd had transferred from VHS to DVD. It was a video of one of our old high school projects. My old computer program changed the format of the content from PAL to NTSC. After burning, we'd tried the copy out on an old TV that was not NTSC compatible and the film rolled like crazy.I'd completely and totally forgot about that!
So, there used to be computer software that could do the job of changing formats but once again the region coding block could come into play there.
