Hey, I really tried my best. For all other people this code works, only 
now we got aware that there's something wrong with the luma-code, which 
explains some effects which could be seen.
Btw., the comparison is about the progress the codecs made, and about 
that what the users get to download from the net. So if you advise him 
to use an older build, this wouldn't be the real case somehow.

Everyone should be aware that xvid is alpha (I clearly state that with 
"my" binaries.).

Btw., I'm reencoding matrix with the "old" luma code ATM and from what I 
can see in the first pass, the results (actual frame sizes) look way 
better. Have to see the first pass size afterwoods though and the visual 
quality of the encoded movie. I guess this really was the error.

So please, let's stop bitching at the persons who dare to release 
binaries and let's see how to prevent to get unreviewed code into CVS.

Best regards,
Koepi
