When I play a DVD using Windows Media Player all works fine (both sound and video).

When I try to play the same DVD in MP I have the following problem;
1. No audio (I have audio in everything else like TV, Music using the sam decoder)

2. On the DVD menu I cannot se what item is selected. In WMP there are a red cross over the selected menu but in MP it does not display.

I have attached the log file (no error log exist).

Regards

More info;
* if I use MPA decoder for audio the audio works.

Why does not the MS audio (Vista) decoder work in MP? It works in WMP.
