Do you have them set up for analog?
ADCON1 =0 (as noted in my setup above?)

What are you using for your reference (ADCON1) ?
ADCON1 =0 sets Vdd as thew ref I believe.

Most of the time, Vcc is not good enough.
If you want really good accuracy, you have to use an external, precision reference.
Really good accuracy would be nice. Right now I have no accuracy.
