new macbook crashes when decoding h.264 videos

[rikscha]

hi,

my new i7 macbook crashes (grey screen) whenever Im converting a video file to Apple TV format.

I tried handbrake, toast titanium and imedia converter. I also tried converting the same video files in windows 7 on my boot camp partition with handbrake and got a blue screen.

in my opinion, this has to be some hardware failure. i went to my local apple store and they checked my macbook on any hardware failures but couldnt find anything.
i just would like to get some more opinions on this problem before I sent it back. i spoke to apple care and they told me to reinstall mac os and see if it still crashes. but since it also crashes under windows, i dont think that reinstalling will solve the issue.
thanks

sounds like a heat issue to me.

don't trust the mac geniuses to be able to successfully diagnose this type of thing either. they're rather useless as far as i'm concerned. while encoding monitor your temps and clock speeds and report back on what you find.
