If you are looking for instructional videos, you should check out the video rental library available to all USMS members. It’s not free, but it is real cheap and it has some of the best swimming videos available.
For a list of titles and order instructions, look under the coaching link on the USMS website.

I don't know what kind of video you are looking for but I ran across this site with little videos from their top swimmers. Best of all it's free...lol. news.bbc.co.uk/.../3097905.stm
This is not free but the TI Four strokes made easy DVD has helped me immensely. My freestyle has gone from hohum to totally relaxed, quiet, long, smooth, and virtually effortless. Swimming has never been so fun. Check for it on ebay. Might be a good deal there for you to pick up.
