As far as well-done sites with a plethora of downloads and information, Mission4today is probably the best:
http://www.mission4today.com/Another pretty good one (doesn't really address IL2 only but...) is flying-legends:
http://www.flying-legends.net/If you register and click the link
"go to downloads section", they have some good stuff too.
You have to take some time to look through them as they have a good bit of information that you have to dig for, but other than being a bit cumbersome, they are really informative sites.
Hope these help.
P.S. - I have many, many IL2 movies I've saved over the years. If there's on in particular I may have it.
