DSLR guys!!!! HELP

[EJdm]

so i bought the canon t2i at best buy a few wks ago and also bought a SD card as well. I wasnt to sure about the SD cards so i ask and they told me the better the SD card the less choppy the video will be so i grab the 2nd best card "EXTREME HD VIDEO" the top card they had was the extreme pro which i didnt really need....so when i record videos it fine watching it on the camera but when i upload it to my computer its choppy like its pauses every second...What can this be? Is it my SD card??

update your PC video card drivers first before anything, and if there is hardware acceleration lower it. if that does not work you could always try another SD card and re-record a video and see if the same problem happens..
