I was kind of annoyed with this too when creating vcd's but overcame it with 
a (simple) hack. After spending about half an hour with the source of lav2yuv 
it transformed 320 into 352 by adding 16 pixels of black to left and right 
side. This black does not show on tv-screen and compresses pretty nicely. 

640->720 would require 40 pixels of black on each side which might make it an 
undesireable effect. Then again scaling 640->720 might have less of an impact 
on the picture quality than scaling 320->352. 640->352 might be okay too but 
(640->) 320->352 by just adding black borders was computationally the fastest 
way(even with a 900mhz athlon I care about this..). And besides I didn't have 
to use bcast to scale anything..

Oh.. I also had to spend and hour to hack mjpegtools to take the latest 
version of quicktime4linux.. a major pain. I wonder if there's any chance of 
the official version going for the latest one since files created with 
bcast2000c seem to be incompatible with the earlier quicktime versions..
