Have you seen that before?
Where do these stripes come from?

I've encoded the movie twice on different machines - both movies have the same errors at some scene changes, but not in the same places! I don't have a proper DVD player sw that allows to view frames seperately or distinctly enough to be sure whether the source *.vob files are "clean", but they appear to be.

Both rips were freshly done from A-Z.

Original movie:
The Abyss (german, region 2)
PAL 25 fps, 720x576, interlaced
german audio: 5:1, 48 kHz
total length: ~ 1:36 (theatrical version)
seems to be Macrovision-protected

Ripping software: Smart Ripper 2.13,
de-CSS, de-Macrovision, region-free, copy IFO

Flash MPEG (v. 0594 AMD-optimized, small time-calculating bug) settings:
512*224 cropped (512*384), resizing: HQ bicubic
DivX 5.01 codec 864 kb/s.
deinterlace, threshold 10, blend
Athlon 3D Now! optimization
Audio: PCM 48 kHz 16b stereo, no audio/video separation

AMD Athlon 1 GHz + Epox/Pronix 8371 686A (VIA KX-133),unreliable machine (must be a nest of bugs somewhere) - ca. 7 fps
AMD Duron 700 Mhz + Asus A7V-133 (VIA KT-133A), good buddy - ca. 5,8 fps

sounds like interlace artifacts
make sure you chose deinterlace threshold of 2 or something smaller then the default. unclick blend unless you really need it. it will only make the encode slow with no apparent effect on video quality that can be seen with human eyes.
the other issue sounds like a currupted vob
if you upgrade to flaskmpeg 6 preview you can cut around it
