You can't have it both ways ;)
Either you have a standard frame size with black borders _or_ you
use a non-standard ("special") frame size and no black borders - there
really are no other choices.

I think it is not a good idea simply because it is a 1 way conversion
(it can not be exactly reversed if you change your mind). The other
reason is that eventually the data might end up on a DVD or viewed
on a regular TV which is an interlaced display.

Then why bother encoding to MPEG-2 in the first place? It would
be better to use the input MJPEG .avi file in Cinelerra from the
very beginning.
After all that trans/recoding it won't make any difference if the
data is deinterlaced or not ;(
Is there a reason you haven't used the MJPEG file with Cinelerra
in the first place? I'm fairly certain that Cin* knows how to
deal with MJPEG files.

MPlayer runs quite well on my Macs ;) Even windoze players have
deinterlacing capability, don't they?
If MPEG-2 is not going to be the distribution format then it is
a waste of time (I think) to first encode to MPEG-2, then import
into another program which will decode the MPEG-2 , export to another
format, and then have mencoder do an encoding to MPEG-4/divx/whatever.
Good Luck!
