well,
step 1: I made an application to get in a loop all the pages (by increasing the tt value http://www.imdb.com/title/tt0000001/), extract and save the rating from each page and then build the dct file.
When the app was done, I realized that this will take days to run, maybe weeks...
step 2: I researched some more, for a SOAP service, or any kind of web service to get this info easier... still nothing.
step 3: scrap step 1 and 2. that won't work.
then I found this page:
http://www.imdb.com/interfaces#plain
they let you download txt files with all the info they have on the website free of charge.
I downloaded the rating file, I extracted the name and the rating and I created the dct file.

How old are you? I was 22 (in 1992) when I first saw a PC and that was when I went to study Computer Science at the University in Bucharest. I fell in love with programming and that is what I do for living now:-) If you wish you cold do this, just start studying. Takes a lot of work... but it's worth it.
