I will send you the log on PPC Mac later, when a friend have made  
some test with
1.9.0rc2 and 1.9.0 just before rc1 (3,4 or 5 days before rc1,  
compiled from CVS)

The slower speed is only on a Mac PPC, on a MacIntel the speed of  
mpeg2enc
is actually the same as the older version.

The version which work come from CVS 3,4, or 5 days before the  
official 1.9.0 RC1 release.

I don't exaclty understand your question, with which version ?

My Config : Mac Pro 2x Xeon Dual Core 2.66 Ghz, 2 Gb DDR2

Here I send you a small log of an encoding with 1.9.0 RC2 which  
produce a very poor quality

Here is the the command line
mpeg2enc -v 1 -f 8 -a 2 -b 9000 -q 1 -o /Users/chris/Movies/MovieGate/ 
mainMenu.m2v -S 9999 -s

And at the end you will find the configure output on my MacPro
