In my case I also could not get a file to play after using
Nero Recode2.
This time it is using Windows XP, SP2 and the file is 10Gb. The file player is Neros' Showtime which surprised me in the fact that the same company's player that produced the MP4 file could not run it.
Since the original post is March 2004 and it is now Sept 2007, I doubt this will help the originator of the msg but it might add insignt to those who search and find this post as I did.
If I later get the thing to play I'll add another post.
