5D mark iii: mins/gb question/issue

[gtoshima]

hi all,

i just got the mark iii and been doing a little testing.

i read that, typically, one can shoot about 45 mins on a 32 gb card, at 1080/24fps all-i.

but, i've been able to put almost 2 hours (1 hour 45 mins) on a 32 gb card....which makes
me suspicious.

am i doing something wrong in settings?

thanks for any ideas.
