Tarek:

There were problems with the 1 litre kits of Xtol not being consistent and 
expiring quickly.  Was it a 1 litre kit you used?  I would investigate the 
5 litre kit and use Mark Rabiner's trick of storing it in 20  2.5cl  glass 
bottles.  Using this method, the bottle you open always has fresh developer.

I assume you are using it one shot and tossing out the spent 
developer.  This is the only way to do it if you are diluting the 
Xtol.  Straight up you can develop the films be reusing the developer, but 
you must increase the developing time after a certain amount of films have 
been developed in the stock solution.

You don't mention the time frame between taking the two rolls of film.  If 
they were not both shot through the same camera on the same day, it could 
simply be an exposure error.

Regards,

Robert
