Hi. 550D videos has about 5 sec. discrepancy, audio is faster then video. It happens at any resolution and speed. Anybody else has same problem? I am using MS Media Player and KM Player, same results.
Clips was shot at 1/60 shutter speed, F8 aperture and ISO 200.

Nope. Directly played with QT and after imported into MC, video/audio is in perfect sync.

After I import into Live Movie Maker, save it as WMF, I got all in sync too, problem is when I am playing .mov file straight from camera. Is this player related then?

Probably. You are trying to play a quicktime file with something other than quicktime. That's not going to work out well in most cases.

You can try the VLC player that handles almost everything. But most likely your computer is too slow to play the .mov files natively hence the discrepency.

You don't want to play through PC from the camera's card a 44mbit file.
