No sound with xvid and divx files with Frodo beta 1

Is it a known issue, I tried to play some videos files in divx and xvid, and I got no sound.

The sound is working fine other videos files (m2ts, mkv)

Also, sometimes the video on divx/xvid just won't show at all (black screen) or I get a white screen.

Am I alone to experience this?

I went back to Eden, and everything is working fine like before, so it is not my computer.
