I had a weird situation on the weekend with a whole set of files that I 
downloaded from usenet.  All the audio was up to 15 seconds in advance 
of the action.  I found out it was related to the black before the video 
started as the sound started as soon as I hit play on the DVD player.

What I found was if I fast forwarded and then reversed, the audio was 
almost synced.

These were DVIX encoded files.  They worked okay on the computer though.

This points to an issue with the software on the player.

File a bug report with D-Link when you get more info.
