[Audyssey] Question for those of you that have purchased Prima games E-guides.

[Yohandy]

Hello everyone,
has anyone here purchased any of Prima Games eguides by any chance? if so, 
how accessible is the format? They use their own excecutable format, and I 
don't want to risk buying one if it will not work with jaws.
The reason I ask is that they're releaseing a Mortal Kombat: Armageddon 
Eguide, and I wanted to purchase it.
Thanks!
