I also uses AC3 passthru..

After applying patch in #730, I can only hear the MP3 track. I don't 
have any channels with DTS to test the DTS part..
Is this meant for Internal playback of DVD or for TV viewing?

attached log below. If you need more info, pls tell..

Do I just apply your patch, or apply both? I only tried the fomer.
