okay, i'm usually pretty savvy about encoding, decoding, and converting media files... but i got these video files with .mp4 extensions that use the Nero Video & Audio codecs (yes, from the company that makes Nero Burning Rom). i can play the files, but i can't get Virtualdub or Tmpgenc to recognize 'em for conversion to other formats. tried googling around, but can't find any info.
Tmpgenc tries to open 'em with my QuickTime reader, but displays an error and the image is all messed up.
does anybody know of a Nero decoder or plugin that's compatible with Virtualdub or Tmpgenc?
