I know it is not exactly what you want, but I would just get a modulator and
make a house channel, then you can tune into that house channel anywhere else in
the house if you wire it up correct, and have a space of several unused channels
in a row. It is not HD, but it is usually good enough, I have a couple of
house channels, on is a mythtv device, and the other is a DTV converter.
I wish an ATSC modulator was made for a PC that could take a pre-existing mpeg2
stream and make a house channel, but no one makes it. This would seem to be
pretty simple to build since you already have the mpeg2 stream.
But without a pre-existing mpeg2 stream you need hardware encoders that are not
a volume item and are expensive.
