Everytime I want to convert ANY kind of source with virtualdub to Divx 5.10 it'll say:
"Cannot start compression:
The source image format is not acceptable (error code -2)"

What wrong? The colordepth of the input video is alright it's 24-bit. A few days ago I was able to convert the same video to Divx 5.10. The sourcetype is:
Divx 3.11 720x576px 24-bit
Mpeg-Layer 3 192kbps 48 Khz

The output got to be the same but a little bit more compressed... Input quality is okay(no blocknoise!!!), so don't worry about that!
