I upgraded the SD card from 1 gb to 2 gb. They are both SD, but the
original one says "Filemate", whiile the new one says (in red)
"Scandisk". Well, then new card DOES NOT WORK. THe camera says the
card needs to be formatted...but when you attempt to format, you get
a "file sys error" code #, and it shows a frozen hour glass. Has a
red flashing light as soon as turned on, too.

The manual shows photo storage capacities, and it only goes up to 1
gb. But at the bottom it says that if using over 1 gb, the video will
stop, and you have to restart it. So it sounds like there isn't
really a limit of 1 gb. card size. I tried this new card in a Kodak
C310 also, and it does exactly the same thing. Is it just a bad
memory stick? What is the top limit for SD card size? Is there any?
