How many minutes will record a Video Camera on a 8gb SDHC?

My camera: http://store.kodak.com/store/ekconsus/en_US/pd/Zi6_Pocket_Video_Camera/productID.145116700 Plan to buy: http://www.officedepot.com/a/products/404975/SanDisk-SDHC-Secure-Digital-High-Capacity/ or http://www.officemax.com/catalog/sku.jsp ? ProductId Y or http://www.officedepot.com/a/products/637578/Lexar-SDHC-Memory-Card-16GB/ would be best for my camera?

none of the memory cards work they are too slow. look at the "c" emblem with a number inside. These are Class 2 and Class 4 cards and will not work for video. so the number minutes is equal to zero. check the manual for the camera, video require class 6 or more.
