[mythtvnz] Myth, LIRC, TelstraClear Analog STB and MCE remote blaster issues

[Sid Jones]

I should have mentioned that I've removed the front panel and have
tried 3 different blaster LED's in multiple positions all with
effectively the same result, damned annoying given the very, very,
very old mythbox worked flawlessly with it's  hauppauge remote until
other parts of the hardware failed.

I'll try some repositioning but I'm sure I'll have no hair by the end
of the weekend.
