I found it quite useful - for a Mac friend of mine.
It's just that when the overzealous Mac users make wild claims, they need to be corrected.
Self-policing might be helpful from the realist Mac users - sadly it rarely happens.
Suggestion though, within native Windows(XP and Vista) ArcSoft TMT is a bit better at most things when playing Blu-ray.
Get a copy and have a go at it with your setup and see if it is any better.
I'm sure the testing will be appreciated by all!
