Voip teleophony - Anyone know Packet-8 or others?

[Neil Schelly]

> I recently looked into creating a MythTV box for HD, but unfortunately,
there are no cable-ready receiver cards, so all you can do is receive
and record OTA (over the air) HD broadcasts, so if you wanted to record
say a Discovery HD program, you are SOL.  When WinTV or Hauppage etc
come out with an HD card that can receive HD  cable programs, then that
is when I will be dumping Comcast's DVR box and make my own PVR.

Why wouldn't this work?

Does that only tune OTA broadcasts?
