[MacDV] Simple? Video to DVD question

[SLarsonIH at aol.com]

I have two basic questions. As background, I'm the one with FCP Pro 4.5 HD on 
the computer that I bought, which didn't come with original media or manuals. 
I have to decide whether to remove it or buy a used copy, before too long.

1-I have VHS tapes of family events and some obscure movies I taped from TV, 
years ago, that I want to put on DVD. Is iMovie and iDVD going to be enough to 
make nice DVD's, or are there some important features that FCP brings to the 
table. For example, if FCP will give more scene selections, sharpen, lighten 
or darken bad footage, much like Photoshop will do with pictures, that might 
make the extra cost and time, worth it. In a nut shell, what does FCP give me 
that iMovie & iDVD don't. (Or a web site that explains it)

2-I see lots of different versions of FCP on eBay for sale, except 4.5 HD.  
Is 4.5 significantly better than 4.0, and is it not as good as 5.0? My 
impression is that Apple dropped a number of programs bundled with 4.5 when they came 
out with 5.0. Is there a web site that tells what came with each version?
