You talk about avi, but your source file (15.mp4) probably is not an avi,
but a mov/mp4 file. This is anyway not related to the sync problem.

Concerning your command line, -D 10 is incorrect. The precision of
the DC component should be changed only for mpeg2. Therefore remove -D 10
from your command line and see if it already helps with your sync problem.

Also if you are using MPlayer 1.0pre8 try with 1.0pre7. There are several
incompatibilities between encode2mpeg 0.5.x and MPlayer 1.0pre8.
Hopefully I will be able to release 0.6.0 soon.

If it is not enough, try the following:
 - add the option -mc 0
 - add the option -mc 10
 - use Mpeg Mode
 - use Mpeg Mode with -mc 0
 - use Mpeg Mode with -mc 10

Let me know if you make any progress.
