Thanks, that worked.

After encoding a few things I noticed that mplayer isn't reporting the video bitrate. Not sure if mplayer or mencoders fault. 

VIDEO:  MPEG2  480x480  (aspect 2)  29.970 fps    0.0 kbps ( 0.0 kbyte/s)

ID_FILENAME=done_1
ID_VIDEO_FORMAT=0x10000002
ID_VIDEO_BITRATE=0
ID_VIDEO_WIDTH=480
ID_VIDEO_HEIGHT=480
ID_VIDEO_FPS=29.970
ID_VIDEO_ASPECT=1.3333
ID_AUDIO_CODEC=mp3
ID_AUDIO_FORMAT=80
ID_AUDIO_BITRATE=128000
ID_AUDIO_RATE=44100
ID_AUDIO_NCH=2
ID_LENGTH=0

The bitrate setting in -lavcopts is definitely working since I can see the difference between 800k and 2300k.  Just isn't showing when looking at the video.

thanks
