Reimar--

I've added the two switches as suggested but they have not helped.  

Here's the line I use from a DOS prompt, which works successfully:
*****
"c:\Program Files\tysuitej\mencoder\mencoder" "morning express.mpg" -o 
me.mpg -noskip -demuxer mpegpes -cache 10800 -oac copy -ovc lavc -of 
mpeg -mpegopts format=dvd -vf crop,scale=720:480:1,harddup -lavcopts

error.txt
*****

Putting that line into TySuiteJ (with a few format changes specific to 
that program) just won't work. The program starts encoding, gets ~4MB 
in and freezes.  I can up the cache amount to a ridiculous amount (eg. 
308,000) and the file will completely process but nothing gets written 
to disk until I abort the program; when I do the file is unplayable as 
(I believe) something doesn't close properly and the file format 
probably gets corrupted. 

The error.txt file that gets written through TySuiteJ gives the 
following):

*****
The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.
Limiting audio preload to 0.4s.
Increasing audio density to 4.
New_Face failed. Maybe the font path is wrong.
Please supply the text font file (~/.mplayer/subfont.ttf).
subtitle font: load_sub_face failed.

Skipping frame!

I've deduced through reading other online posts that the video_out 
device error is common.  It's probably a hook into mplayer as it's 
expecting an output device to be defined (which we're not doings as the 
output is a DVD-compatible file, not a video card).  The same with the 
New_Face error.  The funny thing is that it says frames are skipped but 
I've tld the program not to do that.

At this point I'm stumped.  The program author has given a little 
feedback but has no more ideas.  What can I try from here?
