I was not able to see the delay with my own encoding.

Please run the following command:
encode2mpeg -o as031 in.mpg -avionly -aid 128 -encode 0:3:1 -profile aspl5 -debug 7

Then compress and send to encode2mpeg at users.sourceforge.net the files as031.log and as031.debug.
I will probably also need to play myself as031.avi. Can you put it somewere where
I can download it?
