Logging sector access

Is there software out there that will monitor and log the sectors being accessed during a DVD read? I’m trying to understand an incompatibility between a disc and a piece of software and knowing the sequence of sectors the software is reading from the disc would be very helpful.

I know of 2 commerical programs that can do this:

Bus Hound:

I think spath knows quite a bit on using them :).
