Just viewing the VOBs can give sometimes do this, as without the IFOs, the player doesn't know the format.
If you're getting this phenomenon after starting up via VIDEO_TS.IFO or equivalent, then that's a different matter of course.
Your syntax is a little confusing. You wouldn't have ripped the files with DVD2One; you might have compressed them. Ripping was probably done with DVDDecrypter or the like. So, are you seeing this problem pre or post DVD2One?
