Okay, recommendations for appropriate settings, I currently have the 
following setup:

# MPEG4 specific settings
# Desired bitrate, in bits/second.  2200 means about a gigabyte an hour.
int TargetBitrate=4400
# Scale bitrate by frame size.  If this is set to 1, the target bitrate given
# above will be used as a guideline for 640x480.  Other resolutions will 
# the target bitrate down according to the framesize.
int ScaleBitrate=1
# Maximum quality level.  1 is best, 31 is worst
int MaxQuality=2
# Minimum quality level.  1 is best, 31 is worst
int MinQuality=2
# Maximum quality difference between frames.
int QualDiff=3

The visual quality is both better and worse than the default mpeg4 settings, 
and RTjpeg still looks better.  The 2 problems I see now are that the entire 
picture is soft, ie there are no sharp edges, everything is clear but kinda 
fuzzy like.  Also the frame rate seems lower, like 20-24fps rather than 30.  
What would folks recommend to get around these 2 issues?
