Playing Nero Digital (.mp4) files in MCE?

[John F.]

At home I'm using a Windows MCE 2005 machine in our living room and I'd like to watch the movies I've encoded with Nero Digital on this PC. I already found out that I can watch movies on de MCE PC after these three steps:

- Install Nero Vision Express to have the proper video-codec / .mp4 splitter
- Perform a registry patch so MCE recognizes .MP4 files als videofiles
- Install the CoreAAC codec, because Nero's own AAC-codec doesn't seem to work in MCE. (While it does work in WMP...)

This all works flawlessly, with one exception: when I've got a Nero Digital .mp4 with 5.1 channel AAC-sound, only the the two front channel are played. Proper surround sound doesn't seem to work.

Does this have anything to do with an incompatibility between Nero Digital and CoreAAC? Or is there another problem?

Do you guys know a way to watch Nero Digital files propely in Windows MCE?

Try to check in CoreAAC filter properties to see if there isn't enabled by any chance an option to downmix to stereo/2 channel (as far as I can remember that's enabled by default, at least in the last build I used).

Cheers.

Thanks for your prompt answer. I'm afraid this is going to be a terrible newbie-question, but I can't seem able to find these filter properties. Where can I find these?

(I've tried to Google it, with no luck...)

I found it throught the program DirectShow Filter Manager!

Like you said, there was an option 'downmix to two channels' selected. I've changed that and now everything works fine.

Thanks for your help!
