I ran it on my Rev A, and though the temperature was 186ºF and fan running at 5300rpms, it stuttered during the first minute or so, but ran like a champ thereafter...
Ran it on my MBP 2.5 and it ran flawlessly w/o stutter. What an awesome HD video picture on both the MBAir and MBP...
Were you running coolbook? What version of flash were you using? Your machine isn't refurbished, right?
Thanks for sharing your positive experience
