Some input pins not working?

Hey,
I have 4 input pins, pin0-pin3. The physical circuit is setup the same way for each pin but I can't use them interchangeably. Pins 2 and 3 work fine; 0 and 1 don't. I believe it's because the comparator could be set? Or something like that? I've looked through the datasheet but everything looks disabled. The only initilization I have is as follows:

bsf STATUS, RP0 ;changes banks
movlw b'00001111' ;0-4inputs 5,6outputs
movwf TRISIO ;setting input/output (1=input)
bcf STATUS, RP0 ;changes banks

movlw b'00000000' ;
movwf GPIO ;setting high/low (1=high)

Yes, they're the comparator pins.
