Did anyone of you try the old recommended way (by doom9) to disable the DirectShow multimedia file reader completely and using an Avisynth script as input? I just came to my mind that you have to do resizing anyway when you encode to SVCD from DivX/XviD. Resizing is definitely much faster in Avisynth than in TMPGEnc and I think this is one of the most reliable ways to do the transcoding. Just an idea, tiki4
