problem with divx player

[ddregs]

hi major,

I recently bought a cheap divx player, in order to convert my concert collection to divx, which allows me to save money on dvds and time on conversions.
I just created my first dvd with 5 divx (.avi) concerts , and some of them played while some of the others didn't.
I tried another media but the result was the same.
I isolated the problem taking one of the divx that didn't play, writing it on a cd-rw and the result on the divx player was the same when played: black screen that jumped 10 seconds at a time, and every 3 minutes there is a still screen (displayed on top half screen).
I then re-encoded this divx movie into divx ffmpeg (enabling only high quality) , but no improvement.
I tried xvid ffmpeg but no improvement.
I let my Mac work this night to try xvid mencoder and divx mencoder and I will post the result.
Do you have any suggestions to let this kind of movie play? It's a 23.98 fps, 48KHz mp3 audio, 592 x 320. The chipset of the Divx Player is an ESS Vibratto, and I disabled the QPEL option before encoding because I read on some PC forums that could render the movie unwatchable.
Some PC users suggested me to disable GMC but I don't see any kind of option in ffmpeg.
Thanks in advance for your help!
Cheers

It would be good to know first your results with mencoder.

hi major, just got home
i burned a cd-rw with the same concert encoded tonight with XVID mencoder and it worked flawlessly on the divx player.
any idea or special reason?
thanks a lot for your time

Possibly a requirement of your player on AVI interleave parameters (different on mencoder and ffmpeg).

Thankx for your tip, major.
One more: when pressing fast forward on the above mentioned xvid-encoded concerts, I can't see any image but pressing play I get the video and music (out-of-sync, but pressing the Zoom button on my player resyncs everything.... strange but acceptable)
Is there a setting with regards to mencoder to allow the video to be previewed while fast-forwarding? Any idea?
Thanks once again...

You could find a file which works and then send it to me for inspection.
