For mkv file playback I currently use Haali splitter within WMC, bitstreaming DD5.1 and DTS audio to my receiver. Works great except for files that have AAC 5.1 audio. In those cases, the audio is sent as two-channel stereo. After some research I understand that I would need to use something like ffdshow to transcode the audio before sending it out to my receiver in order to maintain the 5.1 sound.
My question is can ffdshow be configured to perform this task with Media Center's internal player, or must I use it in conjunction with an external player like MPC-HC? I would only want to use ffdshow for this specific audio conversion, and I would like to keep my playback within WMC's player, and not use an external player. Is this possible?
Any tips or useful links would be much appreciated. I'd like to avoid codec packs too. Thanks!
