Hello: I'm hoping someone can help me...been pulling out my hair trying to figure this one out: I was using Shrink v3.1.7 without any problems, and then decided to upgrade to v18.104.22.168. Ever since then, a few of the dvd's I've played in Cyberlink PowerDVD (v5) show slightly jerky video -- and the really odd thing is it only happens in the last few chapters or so. (The beginning and middle chapters are fine.) Also, even though this problem occurs when I'm playing the dvd straight from my player (before I even run it through Shrink), I'm convinced that the new version of Shrink must somehow be involved because the upgrade was the only change I had made to my system. (I had never had this problem with previous versions of Shrink in the past.) I've ascertained that it's not a hardware problem, as I've also tried playback in my 2nd drive (and it still shows the same jerky video in the same chapters). It's also not a disc surface problem because it's been happening in other dvd's, as well. And, again, this all started occuring after I upgraded to Shrink 22.214.171.124 -- I'm convinced that maybe Shrink installed some file that's screwing up my comp's video output. I've already tried going back to the previous version (126.96.36.199) and that didn't fix it. I also tried XP's System Restore and that didn't work either. Anyone experience a similar problem or have any suggestions I can try? I've already googled like crazy trying to find an answer, and nothing. I'm really hoping someone here can shed some light. Thanks a lot!
