questions about the psp 2000 video out feature

[BackBreaker]

does it work on non hdtv's? Do the composite cables hook into the same slots consoles such as the dreamcast or the gamecube use to hook to a television or does it have to be some special plugs only certain new tv's have? Can you play streaming videos from the internet without too many hitches on it? I ask these questions because I am thinking of getting one so I can watch my favorite shows and movies by downloading them off the internet and playing them on my television, would it be worth it for that (I like some games too but dont travel much).

I have a Loewe 9383p which is one of these:

they are not flat screen and it was manufactured in 2003 but it is still a large and I believe expensive tv back when it came out so would I be able to enjoy video with a psp 2000 and composite/component cables or would I have to get the 3000 model? It says they are digital televisions I believe on top of that link but what does that mean exactly? Does it mean they support progressive scanning and high definition? I thought only plasmas or lcd (basically flat screen) did that?
