Yes, you can transfer recently recorded videos with the help of a card reader since the storage type of the Kodak Zi8 is the standard flash card (SD, SDHC). You need to pull the card and then connect it to the PC with the help of a card reader and that's it. The camera features its own software to modify the videos and the data.
However, from what I've seen on the Google Search and related websites, it appears that Kodak Zi8 isn't supported anymore.
