Basically mpeg2enc is telling you can't insist that I/P frames are always 
seperated by precisely 2 B frames (via the -R 2 -P) and at the same time 
insist on a fixed GOP size that doesn't divide by 3!

Setting -g and -G appropriately should fix your problem.  N.b. recent 
check-in's that added smarter GOP splitting logic make -g default to
-G / 2.
