question about "ultra-certified" divx

[maca]

I understand that you can have menus, etc. on a divx disc if it's made with a program capable of making ultra-certified divx, and played on a player that's also ultra-certified. My question is, can a player that's only regular divx-certified at least play the video that's on an ultra-certified disc? I have software to make ultra-certified discs, which l'd like to do for the day when I'll get an ultra-certified player, but only if my certified player can at least play files without the bells and whistles for now.

If the player is DivX-certified, it should - theoretically - have no problems playing video encoded in DivX 4/5/6 or Xvid. It should (again, theoretically) safely ignore the Ultra features present in a video.

It's probably a good idea to check whether or not the target player supports using .divx as a video extension, though. (Even if .divx is usually a variant of .avi.)

Thanks. My player does handle .divx extension as well as .avi. Just wanted to make sure I wasn't making a disc I couldn't play at all without an "ultra" machine.

Only "ultra" machines fully support .divx extensions, as noted above. However, not all Divx certified players can read files with the .divx extension.
