Chris,

Before there is a stormy response to your EMail, you may want to have 
a look at the Infrared FAQ (URL in sig. file) which has a section on 
this very subject :-)

We discussed this issue to death in the run up to Kodak discontinuing the film.

The fault in the film was a manufacturing problem rather than a 
chemical processing problem. Kodak decided to chop the film rather 
than continue to distribute a non-profit making film which had been 
subject to criticism from users.
