Your video card does not have any HD decoding ability so it is all being done by the processor...though I would think the q6600 could handle it... you say the movie is in 720P, but what resolution are you running Windows at and what are you viewing it on?

some more questions:

what file format is the movie in?
do you have the proper codecs installed to playback the videostream?
