[QUOTE="dlthorpe, post: 512467, member: 87069"] Hi All, Can someone please tell me why I cant get 5.1 audio out of WMV files when played in MP if i dont enable AC3Filter as a Post Processing codec? I have tried the setting "Use 5.1 sound for WMV files" but it doesnt do anything for me. With the post processing codec on I get digital sound perfectly. WMVs work fine too. But if i remove it WMVs revert to just a front left and right channel only. MKVs still output digital fine though. Media Portal itself is configured thus... Videos - Video Player: MPEG-2 video: CyberLink Video (PDVD9) H.264 video: CoreAVC MPEG/AC3 audio: MPC - MPA filter AAC audio: MPC - MPA filter DirectShow Filter Control - MPC - MPA Decoded Filter: AC3 decoder: S/PDIF DTS decoder: S/PDIF AC3/AAC/DTS/LPCM Format: PCM 16bit Surely this isnt right as the SAF post says DONT INSTALL AC3Filter FOR FEAR OF DOUBLE DECODING. The other weird thing I've noticed is this with a few movies, The Dark Night for example. If i remove AC3Filter from post processing then the audio flickers on and off at a very fast rate, but its stuttering the sound constantly throughout the entire movie. As soon as i enable the AC3Filter it plays the audio perfectly. So far ive only noticed this on 2 of my movies. Everything else plays absolutely fine. If it helps i can interrogate the file and paste the codec details here? Not sure what you would need so please ask if you are interested in helping :) Thanks for any replies, D.
