I have the Motorola DCX3200 HD box. It comes with an IR remote.

I guess my question is, given my STB, should I pursue channel changing with
the HD-PVR builtin IR blaster, since my STB can respond to IR commands, or
should I go with a channel changing script, which I assume requires a
firewire connection? It's not clear to me if the myth - HD-PVR USB
connection is just to receive content, or if that is bi-directional and can
support commands to the HD-PVR as well. For instance, the HDHR I have uses
the Ethernet connection bidirectionally, both to receive channel change
commands, and to dump content back on the wire for myth to pick up.
