I don't think this MPEG-4 package will come standard with Nero, but more likely a addon that must be purchased. One problem they will face is that Divx and Xvid can be obtained freely on the web, so they will need to come up with a good reason to get people to switch from Divx/Xvid to their codec. The only thing I see different with Nero's codec is that they use an MPEG-4 audio codec, unlike where Divx and Xvid typically rely on some legacy audio codec such as MP3 and in a few cases I've seen: 8-bit telephone quality wave!.
