WHAT: Trying to transcode from mpeg4/mp3 avi to mpeg2video/mp3 mpg

RESULT: Video is garbled and corrupt under WMP and other windows 
players. Seems ok in mplayer.

OBSERVATIONS: avi looks fine in WMP and DivX player. Transcoding with 
Nero and DMC in windows produces mpg without problems.

FILE LOCATIONS:

COMMAND:
ffmpeg -v 0 -b 600 -y  -i 
/usr/local/jakarta-tomcat/webapps/ROOT/test_for_ffmpeg-devel.avi -acodec 
mp3 -vcodec mpeg2video 
/usr/local/jakarta-tomcat/webapps/ROOT/test_for_ffmpeg-devel.mpg

p.s. Sorry for reposting this problem again. I was informed that a more 
succinct post might generate more assistance.
