There is an IPTV tuner being added to MythTV .21.  It is available in MythTV
SVN right now.  I fooled around with it a while ago.  I could tune into a
channel on MythTV as long as it was already being sent to the set top box.
I couldn't change the channel or tune any channel directly from MythTV
though.  Good luck.  Keep us updated.
