be aware that there are various combinations of # of significant digits and leading/trailing zero suppression which can be generated by various programs that don't strictly conform to the specified subset in the excellon documentation. Also some programs, and I think pads may be one, has options that let you use a different origin for the drill file. I call it the "please increase the risk of a bad board" option ;)

With gerbv, you can turn off autodetection of drill formats and manually specify what the format is as well as an offset. By playing with those settings you'll probably be able to clearly see when you have them set right.
