I've ripped many DVDs already, and 95%+ turn out fine. However, a few times the following has happened to me: 1) Rip IFO,BUP,VOB files using DVD Decryptor. 2) It finishes with no errors, warnings or anything of the sort. 3) Burn to a blank disc (similarly no errors). 4) Test it to make sure it's okay, but it isn't. Most of the DVD plays/seems fine. However, some scenes seem to 'jump' or 'stick' and appear a bit blocky while doing so. I figured this was probably because of the burning process, so I'd try a reburn and get the 'jump'/'stick' again in the SAME location. Thus, I can only conclude that it must be the original rip that caused this (and perhaps because of a slightly scratched/smudged DVD). My question is: Has anybody else experienced the same problem? And/or does anybody have any good solutions? Thanks for any help.
