For lack of a better word.
I'll update a pic if necessary, but this is the first time I meet anything of the sort. I threw my spotless Spirited Away vob's into MPEG Streamclip, and the preview bar (and subsequent encode to .mov) showed footage filled with little messed up areas. I'm on a Mac, if you hadn't guessed. This is probably a really common problem, but since I don't know of any steps in between getting your vob's ready and converting them, I have no idea what the solution would be.
Thanks in advance for all help on this!
