Spot on Tom it's a 400D they can't do video as SLRs have a mirror between the sensor and the lens to allow you to look through the viewfinder which is also why most DSLR don't have live view on the screen. The latest ones do but most photographers argree that while useful for low angle shots it's more of a gimick to get compact users to switch. Live view on DSLR's is still in it's infancy and I know most reviews complain the auto focusĀ is slow and not very accurate due to the technology used.
I could go on but it would get boring! In a nut shell if you want decent photos buy a decent camera if you want decent video footage buy a decent camcorder if you want reasonable photos and videos buy a compact.
