Help! Seeking online warbird videos

I am looking for vids of warbirds that I can download/watch online, pages which feature clips of aircraft either in action or from airshows. I especially enjoy modern video of WWII warbirds but modern military aviation is good as well.

I just haven't had much luck finding anything. I've found some pages using Google with one or two clips but I know some members must have a stash of bookmarks.

Oh and if anyone knows where to find clips from airshows with WWII and modern fighters flying in formation that would be extra appreciated. I know they are out there, I have the pics but I cannot find the vids!

Thanks
