There is one possibility -- your vga convertor is trying to do "flicker
fixing" to reduce flicker effects of single-pixel horizontal lines on
output. This will *definitely* screw things up. Look to see if you have
option to turn it off.

It's also possible that your convertor is trying to do vertical rescaling,
so alternating groups of the wrong fields are being displayed.

The final problem is that divx simply does't support interlaced video, so
your chances of getting field order incorrect is high (roughly 50%).

Just forget this divx and use something built from the ground up with
interlaced suppport: mpeg2. And use a dvd decoder card like realmagic
hollywood plus.
