I had this problem a while ago and thought the cause was that I was ripping on one machine and saving the rip to the server. So what I did was just ripped everything directly on my XP server. That worked just fine. I've moved my server now and need to rip on my Vista box. I now get stutter in all of my rips. I am ripping to the local HD and playing on the same machine. The rips that I have previously made work just fine and playing the disc directly with or without AnyDVD is perfect, but the rips made on the Vista box stutter. I tried putting AnyDVD in safe mode, but no luck. Any ideas?
