I upgraded to Nero 6 Ultimate when I added a DVD recorder to my computer and discovered a MPEG-4 encoder was included in the suite. Nero Recode2 is able to copy non-copy protected DVD discs and create .MP4 files that are then playable in Nero Showtime. I also discovered that MS Windows Media Player 9 was able to play the .MP4 files created by Nero Recode, even though not supported by either MS or Nero.
I'm very interested in discovering which codec on my computer is being used to playback Nero Recode2 ".mp4" files. Nero will not offer any help. Their official comment is that ".mp4 files can only be played back by Nero Showtime" and that "Nero Showtime is not sold septerately". This is the only resonse I could get inspite of 6 requests for assistance in identifying the Nero codec.
The encoded quality of the Nero MEPEG-4 files is extreemely good and I want to identify the codec used for encoding since any file I encode with Nero Recode2 can only be played back on the same computer.
A follow-up question will be ... how can I copy the codec to another comuter that does not have Nero 6 Ultimate installed on it?
