My DVD player has a "DivX Certified" logo on it, and also a "DivX Ultra" logo on it. I understand that this means I can play DivX encoded movies on it, but how? Do I just burn a DivX .avi on to a data CD/DVD, or is it something more complicated?

Yes. Just burn the .avi file onto a cd or dvd.

If it's MPEG4 certified you might even be able to get Xvids running on it. Well, maybe anyway.

Why would it need to be MPEG4 certified? I think you're confusing containers with codecs here.

Because DivX, XviD, 3viX and a whole mess of others are (potentially) MPEG-4 ASP compliant video codecs. I'm pretty sure, though not positive, that DivX certification is a super-set of MPEG-4 ASP, so it's pretty likely that your XviD videos will play.

Having had two of these players, I can attest that the majority of problems stemming from these aren't from the video, though. The culprit has often been a weird effect of using avi, the container that didn't originally have support for variable bitrate audio.

*sigh* I pine for matroska compatible players.

DiVX Ultra files are more than just fancy MPEG-4 files. They can contain chapter stops and even a graphical menu. Of course, you need the right software to make these files. I'm probably one of the few people around here who has such software.

I had a DivX-certified player. It can't handle DVD-resolution, higher bit-rate content without getting choppy. So it's basically useless.

As for DivX Ultra, I don't see why they re-invented the wheel. The QuickTime format has had support for chapters, interactive menus, multiple audio tracks and sub-title tracks for the better part of a decade.

Must be a shitty player. Mine can handle 6 hours of DVD-resolution porn on a single Divx disc.

Did Apple go ahead and license DVD players to play Quicktime files when I wasn't looking?

The MPEG-4 container format is actually based on QuickTime, so it might just be that DivX Ultra is implementing all of those "extra" features not normally seen in MPEG-4 files.

MPEG-4 is actually a subset of QuickTime. I don't know if chapters are in the spec, but quite a bit of stuff is.
