Violet stripes in DivX playback

[aLu]

DivX 5 encoded films show violet stripes and patches when played back with Windows Media Player (v.6.4). This only seems to happen with films that have resized AND cropped in VirtualDub. (see picture)

This movie was captured in 768*576 / 25 fps and resized (512*384 bicubic), and a little cropping in both directions was done (504*344). Neither width nor height are divisible by 32. If no cropping is performed, there are no errors, but even if you crop in just 1 direction (height) and the result IS divisible by 32, the image is bad.

I haven't experienced this with cropping only (no resizing), and it happens with DivX 5 codec as well as with Xvid (fewer errors). So after all the cause could lie in the encoding procedure (or the graphic board?) as well. After upgrading to DivX 5 from 4, some of my older movies seem to be "infected" as well. Anybody who has seen this before and some suggestions where it comes from ?

Hard- and Software:
VirtualDub 1.4.7 (release version)
Creative Vanta (TNT 2)
DivX 5.0 bundle (with DivX Player alpha), divx.dll v4.0, divxdec.acx v5.0

Encoding settings:
780 kb/s., keyframe every 75 frames, no psychovisual enhancements
No audio compression at the same time

I think it's generally adviceable to always encode at a resolution divisibe by 16.

I would suggest that you try upgrading to divx5.0.1.
