    My xbox wont play mp4s with 5.1 so i have to downmix to stereo. Anyone got any thoughts?

    I don't really want to do re-encodes. I'd love to just passthrough the video, but i can't find anything that will do it.

    FFmpegX aborts (could be me not doing it right) and handbrake wont passthrough the video.

    I can do it in quicktime pro but it flattens it in a really weird way, the music is fine but the speech is all in the right channel. This is actually specific to one file I have.

    I'd just like a little more control and comfort that i'm not losing anything.

    i use rivet.

    As far as I understand it, it's a limitation of the xBox or mp4 or both.

    Whoa! When did twonky go OSX! Cool. Thanks.

    jesse- it's a limitation of the xbox 360 h.264 codec.

    iVideoConverter will do the trick.

    I use the app to downmix my MKVs from DTS 5.1 to AC3 5.1 for my WD TV. You can downmix audio and do video passthru etc.

    Thanks chicken, that almost worked.

    Apparently though only AC3 audio streams can be resampled, this file would appear to not be that. Listening to it in VLC all the speech does appear to be in the right channel even in 5.1. Weird.

    I like Twonky as a server but it doesn't really fix or have anything to do with the problem I asked about initially.

    eh? Only AC3 audio streams can be resampled? As I mentioned in my first post, I downmix DTS 5.1 audio to AC3 5.1... even AAC Stereo... quite a lot and never had any problems i.e speech not appearing in the right channel.

    Did you choose the proper output audio to stereo?

    I think it was just the particular file. It wouldn't let me convert the audio to stereo. In the end I converted it to a .mkv with AC3 5.1 and then back to an mp4 in stereo.

    Anyway, thanks for the help.
