         It seems to me that there ought to be a way to use the ATSC 
tuners to

     pull

         in the compressed stream from the air, let MythTV backend send 
it out to clients in UDP, and let the client ends decompress the streams 
however

     they

         want. Am I missing some technical detail that makes this all 
not

     possible? Well, it is not a MythTV solution, but if you look at the 
SiliconDust TECH models, they can multicast the streams to anyone 
configured to listen to the (ATSC, compressed) stream.

The next round of HDHomeRuns are going to have built in transcoding.  
I'd
wager they will also make a version with multicast support.  You may be
able to get completely away from having a server allow users to recieve 
the
transcoded stream directly from the HDHR.

Thanks for the replies.  I'll look into them.  For anyone else with my 
same need, I believe I found an open source (GPL2) solution today, 
MuMuDVB.  It promises to stream DVB streams via multicast, direct from 
the 19.4 megabit OTA signal, as well as transcode to any standard 
CODEC's seamlessly.  I'll go play with that and I'll stop spamming the 
MythTV guys.  (-:
