We gave up a long time ago with playing the audio recorded OTA on ATSC 
stations directly.  I see you are not in the states so I don't know what 
may or may not work for you.  I had thought many had resorted to 
transcoding their video on the fly using VLC when serving them up to a 
mediaMVP box.  At one time I had thought I would schedule transcoding 
everything I recorded on my mythtv setup to a lower quality bit rate and 
stereo format (compatible with mvpmc).  But I never got around to it.  
And now I feel I would be giving something up on the front ends that can 
handle the higher fidelity video and sound.

I am not familiar with feeds that contain both the MPEG2 audio and AC3 
audio.  But I am siding with the thought that the mediaMVP box may not 
have enough Ethernet bandwidth to keep up with so much data.

I would suggest you google and hunt down the "recipes" for transcoding 
on the fly when the client is the mvpmc.  It has been done and I am sure 
you will find several descriptions on how to do this.  At that point you 
can probably get rid of the AC3 component of the stream if that is what 
is giving you problems.

-good luck
