video compression under virtualdub HELP!! (xvid codec)

[limitless]

Hi I've posted this under Editing, Cutting and Joining but am really not sure if i posted in the right place because i didn't get any replies, also i just registered on this site so now I have to try this section too.

My problem is that Im trying to change the resolution of this avi file with virtualdub but in order to do that, I need to use the "Full process" mode under "Video" in order to enable the filter "resize", after resizing and saved my new avi to a new file (the 2 minute video became 1.2gb large with a resolution ov 5xx (H) and 3xx (V), because the video is uncompressed after the resolution change), now obviously i would want to recompress the avi with xvid.

Under Video - Compressions - xvid codec compression options, it lets u select the "desired bitrate", i've set my desired video bitrate to 169 kbps but and audio to direct stream (original audio is 128kbps), but after compression my video becomes around 30 kbps only?? why isn't it 169kbps like i set in the options??

what did i do wrong?

Thanks in advance

EDIT: or tell me what other codecs besides the Xvid codec can compress decent videos, im so stuck !!
