Thanks gusangora, The pad direction codes are working now which is great.
I'm getting a nasty delay though, and sometimes I have to press twice before the PC reacts. Is that normal?

Stupid question, but what are the .imo files for? Are they for Win Media Center?

I found a pdf of the imon ir spec on a different thread so I'm going to try a decipher these codes today. I have the hex codes for each command that the VFD recieves from my linux config files. They are all like '0x289395B7' but I should be able to translate them somehow.. we'll see.
