Interesting - although it is strongly recommended that frame dimensions
be multiples of 16 that is not enforced by the MPEG encoder mpeg2enc.
Must be something in the JPEG processing that is imposing the
restriction.
But why are you using yuv2lav in the first place instead of
encoding to MPEG-1? MJPEG is much larger than MPEG (as you've found
out ;)).

Encode to MPEG-1 instead of MJPEG.
Something like this (which is just off the tips of the fingers - I
haven't actually tried it ;))
jpeg2yuv ... | mpeg2enc -f 0 -b 800 -o output.m1v
If 800 Kbits/s is still too large I'd lower it. With a small frame
like 128x96 you probably can get by with 400 or less.
Lots of other options can be tossed in but that should get you
going in the right direction.
