I spent about 16 hours last week generating codes with IR Scrutinizer and documenting an XCF file as I tested all 128 functions across multiple Pair IDs for the new AppleTV boxes.
Sure, it is not fun but MakeHex and the newer IRScrutinizer make the job alot easier. IRScrutinizer will even generate a CCF file that can be imported into PEP1. Sure, you need to use a stylus to test but it surely works.
