Works on S60 v3 but not on Palm Zire 71

Hello
i'm trying to play a movie in Palm Zire 71 but im receive the message:

No codec for video format:
"DIVX"

The same video works on Symbian S60 v3

Software version is "DivX Mobile Player version 0.87" in both platforms Palm OS and Symbian and the movie is the same too.

It was coded using following command on linux
mencoder -ovc lavc -lavcopts vcodec=mpeg4:autoaspect=1:vbitrate=512 -vf scale -zoom -xy 320 -oac mp3lame -lameopts abr:br=92 -af resample=32000 /source.avi -ffourcc DIVX -ofps 25 -af resample=32000 -o /output.avi

What is wrong?

Palm Zire

Sorry the error code isn't very helpful, but I believe the problem is the limited memory available on the Zire. DivX Mobile Player will report that no codec is available if there is not enough available memory to load the codec.

The most recent fourCC for DivX is "DX50" but "DIVX" is also a valid code. I haven't tested a Zire 71 but I'll try to look into it.
