From what I've heard the Kiss player will do Divx out of the box, don't know if it supports it on DVD disks though. I have a little Koss Portable 216 dvd that will play MP3's off just about any format of dvd nedia I burn them to, the other machines wont do that, but it won't play divx directly, MPG, no divx.
It's been fun trying different media formats and burning methods to try to see what works with what and what doesn't
At least the Sony has plugged right along so far, no bad disks, no heat problems, just works.
I have been doing Invader Zim episodes to SVCD, I should run them all to a dvd RW and see if they work.... Then put some MP3's and MPG's too, if a player handles it all it can do most things....HMMMM
