digital inputs: some bad?

[Trav-O]

ok, so I heard a rumor a long time ago that the higher number rc digital inputs have questionable functionality... is this true?

the reason this concerns me is that i'm trying to get signals from my IR board... The board does give signals when you press the corresponding buttons on the remote controller (i've checked with a multimeter) BUT the code doesn't seem to want to register the signals... (btw, there are no code errors. I'VE CHECKED! trust me on this) when we replugged the pwms into digita inputs 1 2 and 3, the switch 1 2 and 3 leds came on, binking when we pressed the remote controller buttons so yea...
