Actually I need to get it working period.

I have demuxed the MPEG2 file as a m2v from the original VOBs, upped the priority of the 'CRI Sofdec' in TMPGEnc. But I still get the 'Unsupported' Error, like the Decoder doesn't exist.

I downloaded the TMPGEnc that comes without the Installer, but I don't think that's the problem. Also the m2v file plays fine in WinDVD.
