DSLR and Camcorder or recording DSLR?

I have a Nikon D5000 but am thinking of selling it because it doesn't autofocus in videos or autofocus very well or fast when taking pictures. I'm thinking of getting a Sony A390L or A290L and get a Toshiba palm camcorder (camileo x200 or x400) OR getting the canon 1100d or 550d but the only thing I have against the canons are they may be slow to autofocus when taking a picture (do you know about this?) and the noise whilst recording. Thanks in advance.

Added (1). I know how to use my camera, maybe not to the ability of a professional photographer but I don't want or claim to be one. The main problem I have is FOCUSING WHILST RECORDING WHICH IT CAN'T DO. I like the Sonys because they focus BEFORE you start to press the shutter button down when taking a picture. Also I can't manually focus whilst I'm recording myself or whilst I'm away from the camera can I?

I'm putting this to the vote because I don't believe that there's a best answer as you were either rude or unhelpful.

What? DSLRs only have slow auto focus when using live view. For video, definitely go for an HD camcorder. The Vixia HF R21 or HV40 HDV are two good choices.

Are you using live view? If you are get off of it and into using the view finder. You'll find the auto focus speeds up considerably.

Most dslr cameras don't auto focus during video and to be honest you really don't want it. While recording video with auto focus you'll find that every time you move the camera or every time any subject in the frame moves the camera will struggle to find a focus point. When you play back that video you'll find it weaving back and forth between focus and out of focus… It's not a good feature at all.

So, I suggest, first get into the view finder if you're using live view. Second learn to manually focus the lens you have.

So many people expect a camera to do everything for them and that's not the case with dslr cameras.
Regardless of brand dslr cameras are all basically the same. They are intended for serious photographers who know how to operate them. If you've not learned the basics of using one of these cameras then I'd say the entire problem is caused by your lack of camera skill and has nothing to do with the camera.
