Since a lot of people here in the U.S. have DirecTV, I decided to
create a plugin to handle sending IR signals to a DirecTV receiver. So
far this plugin has worked quite well on my friend's Freevo box. I've
attached the plugin and a patch for config.py to add the irsend_trans
setting, described below.
The setting "irsend_trans" has to be added to the TV_VIDEO_GROUP which
belongs to the DirecTV external tuner to make everything work correctly
with the IR transceivers that come with the Hauppauge MCE Kits. These
IR units have 2 blaster ports. One port _should_ be selected for use
with the DirecTV receiver. The other port could be used with a VCR or
other IR controlled unit. If the IR port on the transceiver isn't
selected, BOTH blasters fire (if connected), potentially causing
improper behaviour of the DirecTV unit.
I'm working on moving the core IR functions out into a separate plugin.
