it's the opposite: it's too short for NTSC, that requires 18 frames for 
GOP.
Those messages are harmless, but you can still override the video bitrate
setting -mpegopts format=dvd:vbitrate=7000.
BTW harddup should be the last filter afaik, and adding :mbd=2 to 
-lavcopts will
produce a better looking encode.
