Digital photography

To any 550d owners, what memory cards are you using? i just brought a scan disk class 6 16gb card that doesn't work too well when recording film (i.e about 5 secs before it gets overloaded) apparently certain models work better than others.

Fujifilm 16gb SD/HC 6

Looks like the image below, but with a '6' in the circle and not a '4' as in the image.

Works fine with the 550D in video mode, no problems at all.
