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.
