Here is the schematic, tha only “hard” part is to find someone that has a PIC programmer.
Depending on which is your PIC you have to set this on the programmer.
- PIC12C508/509: OSC XT for use with quartz, OSC IntRC for internal oscillator; WDT ON (watch dog timer); MCLRE INT (internal startup)
- PIC16C84/F84: OSC XT; WDT ON (watch dog timer);PWRTE ON
Software can be downloaded here. UIRhex (rename to zip)
All the credit(software/schematics) goes to Srđan Milostić I’ve just “created” a mirror.

Seems a little bit harder to use just arrows in Windows Media Center, despite the beauty I suggest you to use a remote control with more buttons.. otherwise go Boxee
