Can't get MP4 to play in surround in WMC but MKV does

[VGLance]

I'm using all HDMI from a brand new HTPC with a Denon receiver and 59" Samsung SmartTV plasma, all components very new and high quality.

No problem getting surround working on MKV's but no dice on MP4. Here are the details on the movie:

Try using Metafox from Shark´s tool page (http://shark007.net/tools.html) to change the file from mp4 to mkv.

be sure you have selected the proper speaker setup in Control Panel | Sound
On the SWAP TAB, disable both of the Micorsoft Audio and Video decoders

I use this machine as a DVR in addition to an HTPC, I also have a ceton echo media extender in another room. Will disabling those MSFT decoders cause any issues with live tv or recorded tv playback?

as soon as you test what I suggested and report back, we'll all know
if it fails you, use mad's suggestion

Ok I tried both methods and they don't work. The program seems to convert the mp4 to mkv file perfectly and in the properties of the file I still see 6 channel. But it's aac. ac3 6 channel mkv files work flawlessly. Is there maybe a way to convert aac to ac3?

I read ffdshow is supposed to be able to convert the audio through hdmi, but there's no ffdshow option as the codec to use under the mkv tab.

Great! This did the trick, although I had to do one more step in turning back out the Microsoft Audio Decoder in the Swap tab because it totally prevented WMC from working without having that on.

Thanks Shark!
