Hmm, -q 2 and -b 2400 ?

for maximizing, I don't think that you should start with such a high q value. 
Of course, mpeg2enc will lower it dynamicaly (as other mails mention, too), 
but you could still waste bits for -q 2 for scenes which will force the 
encoder to go lower where the bits would be spent better. For -q 2, higher 
bitrates settings are needed.

Also, you lower the default SVCD buffer setting with -V 200 (is it not 230 ?), 
which can result in "likely buffer underrun at ...", if it is not needed for 
your specific hardware player, i see no real reason for this.
