I got this problem when i play a mpg2 with mp2 audio for quick testing with media player 2 that the player tries using the ac3 filter to play the audio causing the computer to use 100% resources,the only way i can fix it is uninstalling the ac3 v7 filter.Is there a way so that i can set powerdvd`s audio decoder for the audio playback so when i install the ac3 filter it doesnt try playing the mpg2 audio such as hacking the registry?
