I just tried a transcoded show using wmv2 and both pocket windows media
player and pocket divx both say it's an invalid video format. The
mencoder command was:
mencoder -ovc lavc -lavcopts vcodec=wmv2:vbitrate=300:vhq:vpass=1 \
-vf scale=320:240 -oac lavc -lavcopts acodec=mp3:abitrate=128 -ffourcc \
DX50 -o $VIDEODIR/pda/$TITLE-$STARTTIME.avi $VIDEODIR/$FILENAME -quiet
Just to make sure it plays somewhere, vlc plays it back fine.
I'll try msmpeg4 next.
