I have some that I got as a free download around a year ago that are quite good. If you send me an email at tserface@sbcglobal.net, I'll send you the .zip tonight in an email if you'd like. There are around 4 or 5 to choose from. I don't remember where I got them, but they were designated as free for distribution so I'm OK with emailing them to you.
If you still have the American flag video I could sure use it. I am putting a video together for my church's July 4th program (performed on 6/27) that features our servicemen and women and am in dire need of an American flag video.
I've even used these low res versions in a pinch (found in the temp folder once viewed--with other images composited over to hide the lower quality) and then purchased the set later.
You might contact their Director of Marketing for a deal on just one flag - who knows (nice guy).
