[mythtv-users] trouble transcoding to FLV

I use the following with my script for a program I call Mythtube:
mencoder -ofps 12 -of lavf -lavfopts
i_certify_that_my_video_stream_does_not_use_b_frames -oac lavc
-lavcopts acodec=mp3:abitrate=32 -channels 1 -srate 22050 -ovc lavc
-lavcopts vcodec=flv:vbitrate=200:cbp:mv0:mbd=2:trell:v4mv:predia=2:dia=2:last_pred=3
-vop spp,scale=360:240,harddup -o
/data/www/html/mythtube/$TITLE-$STARTTIME.flv $VIDEODIR/$FILENAME

Here's the post I did if your interested in the flash streaming
(Mythtube) I setup:
