Are you using option 5 (Export to VCD)?  I've never seen choices on
resolution size, mp3 bitrate, or cropping. If I choose "Export to SVCD"
then it gives some of these options.  When I use K3B to burn a video CD
from my exported files, it says that it is 352x240 MPEG1.

Just for grins, I tried different "export" options on the exact same
show (I've never done this before).  Here are the results:
Show Length (after cutting commercials): 20:45 (min:sec)
VCD: 352x240, MPEG1,  Export Time: 21:05
SVCD: 480x480, MPEG2, Export Time: 41:57
WMV: 640x480, audio bitrate 128, video bitrate 256, Export Time: 10:49
DivX: 320x240, audio bitrate 64, video bitrate 256, Export Time: 8:24
DivX: 640x480, audio bitrate 128, video bitrate 256, Export Time: 10:41
DivX: 640x480, audio bitrate 128, video bitrate 512, Export Time: 10:47
DivX: 640x480, audio bitrate 256, video bitrate 2048, Export Time: 12:05

(I didn't use noise reduction or deinterlacing for any with that option)

Interesting to note that the last DivX was half the time of the MPEG1
(VCD), right in between the VCD and SVCD in size, and slightly better
than the SVCD (MPEG2) quality.... while taking just over half the time
to encode as the MPEG1.

Other than the SMP, I don't see anything..... unless it's my normal
nuvexport export choice (and its resolution).  Well, maybe it's in my
transcode/codecs.  I use transcode, and codecs, from plf.zarb.org (for
Mandrake) which may (or may not) have some extra "goodies" in it.
