Some dslr can shoot at Full HD, so you get 1080P, but recently some compact point and shoots are coming out with 1080P also. But form what I have seen, the higher quality lenses of a DSLR system gives the DSLR a edge in image quality. Seems like canon has produce some really good dslr with full HD, that they are using them to film music videos and TV programs now.
But if you are just looking for youtube HD, a compact point and shoot will do a nice job, and a lot less cost.
