I did an update/upgrade yesterday of my 8.10 system and the functionality of my Gyration GYR3101US deteriorated.
Specifically, volume up and down did not work nor did the mute although I think volume down caused MythTV to turn off. The power button did nothing and the pause acted as if the Windows button had been pressed.
The #59 entry of the 1812 template matched the entries in http://forum.linuxmce.org/index.php/topic,11871.msg83769.html#msg83769
It looked like the entries that Seth noted as different http://forum.linuxmce.org/index.php/topic,11871.msg83808.html#msg83808
were the ones that I was having problems with so I updated the 1812 template with them and did a Quick Reload Router and now my remote works as expected again.
Now the question is why is the behavior of my remote different than others?
