What I noticed is that if the frontend is displaying the channel, or the
windows vompserver is streaming it, when I call up the channel on my non
ac/3 complient vomp box via streamdev and iptv, (which works with my
internal atsc cards), the ffmpeg diagnostics report that I have no audio
in my audio stream.  It see's it as ac/3 but gives it 0 channels, then
fails to convert (I had it converting to mp2 and throwing the result back
into the iptv plugin, so the remote frontend can play it.

When I get home I can show the ffmpeg diagnostic output with a pci card or
the hdhomerun if it'll help..
