Basically, my .avi files are re-encoded perfectly, but if I try to re-encode .mp4 or .mkv, then they play at 10x their normal speed. I haven't tried WMV yet. I've tried using CCCP and ffdshow-tryouts independently. DGPEnc can't open the audio streams even from my .avi files. I want to get BatchDGP working before I try SUPER, which I've read causes buffering issues on the DS. I would rather not have to re-encode to AVI, then re-encode again into DGP due to quality loss. Yes, I've followed the BatchDGP guide.
