I have two films that are XVid DVD rips. Gspot does show some differences. One movie worked fine using TMPGEnc DVD Authoring to make a DVD-R but the other came out jerky as hell. Almost like it's doing each frame twice with a slight pause between each. Both played perfectly in Windows XP. So I tried using TMPGEnc to convert it first same result. Tried using Virtualdub to redo it first but still no luck. Help please anyone.
