Ok, so here is what you can call a full bugreport:

And now, let me describe the problem:

This is not a problem with compilation/playback, I do not have any segfaults, 
SIGILLs, signal4, coredump, etc. Mplayer just worsk fine. It's about 
mencoder.

mencoder version: MEncoder CVS-020608-12:10-3.0.4

I had never experienced this problem using pre3 and older cvs distribs. pre4 
seemed to start thisone.

I have a 2cds SVCD to compress to Divx, no crop and special effects needed. 
The movie is about 1,5 hours long, as the original movie size is correct:

773122756 May 20 21:05 e-dtox1.mpg
759604048 May 20 21:17 e-dtox2.mpg

I'm trying to do a 3 pass encoding thisway:

cat *.mpg|mencoder -ovc frameno -vop scale=576:432 -lameopts abr:br=96 -o 
frameno.avi - >frameno.log
cat *.mpg|mencoder -v -vop scale=576:432 -lameopts abr:br=96 -ovc lavc 
-lavcopts vcodec=mpeg4:vbitrate=964:vpass=1 -o pass1.avi -
cat *.mpg|mencoder -v -vop scale=576:432 -lameopts abr:br=96 -ovc lavc 
-lavcopts vcodec=mpeg4:vbitrate=964:vpass=2 -o pass2.avi -

mencoder tells me at frameno that I'll need to do a 964 bitrate to make the 
movie fit to a 700MB CD. This looks perfect as information, it is possible 
because the movie is not that long. Pass1 encoding produces pass1.avi which 
is not even close to 700MB:

344541244 Jun 10 05:33 pass1.avi

It is the same with pass2:

332587324 Jun 10 08:11 pass2.avi

It does not metter if I change the bitrate. It will be the same size whatever 
I do even if I take 10 times of frameno's information (9640).
There are some movies affected, some are not. I have no idea what makes the 
difference, I'm trying to encode SVCDs only and as I've already mentioned did 
not have this problem before.

Please let me know what files do you need to give me some support. I can 
support you with the frameno log, lavcstats, everything regarding the 
encoding process...

Kind regards,
