Quality Full HD Camcorder - DSLR or dedicated one?
The Canon 5D mark 2 opened the world to the abilities of DSLR shooting video. But if you read the real world discussion, you will find that taking amazing video with it is a serious challenge. And it takes only about 15 minutes of video at a time, so your 1 hour++ is simply not feasible. 

The 5D mark 3, just announced and $3500, doubles the video time to about 28 minutes.

Things like auto focus are a ton easier with a camcorder.
