[mythtv-users] MythTV PVR-350 / TV Hookup Connections Help

[Jason Hunt]

Thanks, that was very informative.  How can I find out more information on a
IR blaster?  The DirecTV box does not have a serial port, so I assume this
is the only way (besides changing to the channel manually).  Again, thanks
for your help.
