Hi Giacomo,
thanks for your input.

Because I don't understand these options anyway I removed them.

I tried to remux the files with both mplex and tcmplex to no avail. Both
ended with lots of noise.

Yes Sir! Plenty of space at the moment.

I'm encoding the movie again. Let's see what the result looks like. Now
I used:

mencoder -sws 9 -vf scale=720:480,harddup -ofps 30000/1001 Loose\
Change\ 2nd\ Ed\ Divx.avi -nosound -ovc lavc -lavcopts
dc=10:vqmin=1:aspect=16/9:vcodec=mpeg2video:mbd=2:keyint=12:vrc_maxrate=9800:vrc_buf_size=1835:vpass=1:vbitrate=5230
-o /dev/null -of mpeg -mpegopts format=dvd && mencoder -sws 9 -vf
scale=720:480,harddup -ofps 30000/1001 Loose\ Change\ 2nd\ Ed\ Divx.avi
-nosound -ovc lavc -lavcopts
dc=10:vqmin=1:aspect=16/9:vcodec=mpeg2video:mbd=2:keyint=12:vrc_maxrate=9800:vrc_buf_size=1835:vpass=2:vbitrate=5230:
-o test_vid.mpg -of mpeg -mpegopts format=dvd

I'll reply in a few (~3h). Something bothers me, though. I can't tell if
it was "trell:cbp:dia=-10:predia=-10:vqmin=1:lmin=1" or "harddup" in
case the result works fine this time, can I? Well, I guess I'll invest
some more in this matter if the result works and if you want me to.

Cheers
Sebastian
