[mythtv-users] Changing bitrate with avidemux2

I know there are some folks out there that use avidemux2 to manipulate 
their MPEG-2 recordings... I have a quick question:

I've been using nuvexport to transcode my 480x480 RTjpeg recordings to 
SVCD.  It's worked well.  Now I have an M-179, and want to make an 
SVCD.  My recording profile is set to 480x480, and I've already used 
avidemux2 to cut the commercials (on keyframe boundaries).  Now I need 
to turn down the bitrate to something in the SVCD range.  The question 
is, exactly how do I do this in avidemux2?  I looked at the Video Codec 
options, and there was an SVCD preset.  However, I have to choose 
between setting the bitrate or setting the quantization.  Which do I 
want?  Is one faster, or will one give better results?

Hopefully I'll only need to do this on a few recordings, as I'm changing 
my profile to record at 1/2 D1 so I can burn CVDs instead of SVCDs.
