Is anybody else noticing that Amazon Instant video destroys the macbook battery and heats the thing up? On HD it eats up over 50% cpu while on non-HD it eats around 30%. The thing is either way the machine gets realitively hot and battery life is like 4 hours. Anyone else getting this issue? I am on the latest OSX. As a comparison flash with the crackle website uses only 15% cpu and does not heat up the computer.
