Making plans ahead of time & self addressed stamped envelopes are a good way to go!
But (for me) when depending on the schools to get me the film, I'm receiving less than 30% of my games & it could be weeks to months later and in some cases not even the game that I worked.
That kind of defeats the purpose of video review as 24-48 hours after the game is recommended.
I've found the best way to get film is to bring your own camera, tripod & camera person.
I heard good things about Archos as well
