Additionally, if you need clean IR Codes for the
MCE commands, I do have an Excel Spreadsheet posted
in the files area. You will need to dig a bit
for it, but it is there.

Since MCE uses two RC6a codesets, if you turn
off the key debounce in the registry, you are
probably better off using all the codes from one
codeset. If you "Learn" from your MCE Remote,
there is no way to know or to control which codeset
you learn, and for instance, if you need to repeat
your "learn", the first one will be one codeset
and when you press the key the second time, it
will be the other.

In addition to the spreadsheet, I believe somebody
also discovered another undocumented command at
code #80. You can use the IR Code Generators
referenced in other threads to create the code
for #80, or any other one not listed in the spreadsheet.
