Nero has supported DivX 4, and DivX 5 for quite some time, as well as Xvid files, so there should not be a problem.
I downloaded the file, but Windows Media Player would not play this file.
And Nero Showtime would not play it either if I just click on play, but if I use the mouse to jump forward in the video, say the middle, it then begins to play and you can here the audio from Bart Simpson and Marge, but no video plays. This file does show that its an MP3 audio stream. But something is causing it not to play at the begining, and not video at all is being displayed. Ran into the same issue with PowerDVD 6.
