Right now I see two ways to solve your problem:

1) Do small printouts in your tested program[1] that can be enabled in
compile time through C macros (#define) or run time through a command
line option. Compare the printouts when you recorded with the printout
from when replayed.

2) Use the -ep and -ek options. I just discovererd a newliy introduced
bug in them so hold on for a short while, will fix it asap. An example:
   -ek F5 -ep ""

  2.1 Make a script ( that takes a snapshot of your
display and stores it somewhere.

  2.2 Every time you press F5 during record, Xnee will
   * add a mark in the recorded file (see below) together with
   * launch[2]

  2.3 Move the image somewhere else.

  2.4 When replaying Xnee will eventually read the special mark in the
recorded file. When reading this Xnee will launch

  2.5 Compare the image from the recorded session with the newly
replayed session.

... could any of the procedures above help you???

[1] one can argue and say that the program you're testing is not the
same as you 'deliver' to your customer. Make sure the printout does NOT
interfere with the programs normal work!!!
