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 ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
