You may have a bad solder joint somewhere. I remember on one of the prototype boards I was having all kinds of problems. Turned out a little blob of solder was bridging the legs on an IC. The fact that you've got a warm/hot IC may be worth investigating -- that was one of the symptoms I found too.

I uploaded a commented copy of the MCU code to the files section.
The calibration code is at the end of the program IIRC. If you really
want to understand what it is doing, I suggest you look at the code
and my comments.
