With mencoder (on Linux) I've made DIVX copies of my DVD library and
hoped to keep them pristine as masters while using the DIVX's in my new
Norcent DP-220 that I recently bought online. I'm finding that these
Divx AVI's play on the Norcent with a nasty audio delay that is
sometimes around 4 or 5 seconds. The AVI's play fine on the Windows
DIVX playing software, btw although in linux they do play with a 1
second delay perhaps but that's adjustable via Mplayer when playing.

To fix these AVI's I used avisync from transcode to no avail (but I'm
still experimenting). I also used transcode itself to do the Divx
encoding but I'm finding that trancode appears to create larger sized
files which kinda defeats the purpose in the first place.

This is the 3-pass technique that I've been doing with mencoder:

mencoder dvd://1 -alang en -ovc frameno -oac mp3lame -lameopts
cbr:br=96:vol=6 -o frameno.avi

mencoder dvd://1 -alang en -oac copy -ovc lavc -lavcopts
vcodec=mpeg4:vpass=1:acodec=mp3 -o filename.avi

mencoder dvd://1 -alang en -oac copy -ovc lavc -lavcopts
vcodec=mpeg4:vpass=2:acodec=mp3 -o filename.avi

You'll notice that I use constant bitrate for audio since I know this
can be a sore spot for the Divx players.

Can anyone tell me if I'm doing something wrong or whether this is an
issue with the Norcent player. Nobody on Amazon mentioned this A/V
sync issue and instead fell over themselves praising the unit. Please
note that DIVX's that I've downloaded play just fine on the Norcent, so
this makes me think its something that I'm doing.
