Now that I've transferred hundreds of songs to my new iPhone, I'm eager to have a few videos on it as well. If you scored an 8GB iPhone, you should be able to roughly store up to 12 hours of video, whereas a 4GB model can hold about 8 hours (this all depends on how much memory you have used up with songs and pictures, etc). With the iPhone's portability and bright, wide screen, having a few of your fave videoes to watch on the built-in video player is a must.
A new software program called DVD to iPhone will take any DVD and convert it to an iPhone friendly format. Featured on Popgadget, you can also use this software to convert recorded TV, downloaded YouTube content, or videos from your camcorder. It only runs on PCs with Windows XP, NT Vista or Windows 2000.
