I've spent an hour or so with Google trying to find a way to add tags to QuickTime .MOV files from my Canon SX1 IS camera. I've gotten rather addicted to the fact that I can easily add tags to photos in Vista. I'd very much like to do the same for my videos but haven't found a way. Apparently it's possible, although a bit clunky, to do so using QuickTime Pro. I saw a similar request in a different area of this forum, but it wasn't answered because the person seeking help was trying to tag videos he'd ripped from DVDs. These are original videos I've shot myself. You can see a few samples
here.
The next step is finding a program to edit these videos. I'm currently using Windows Vista Home Premium SP2 on a Core 2 Quad system, although I've been giving some thought to getting a Mac. I've used Pinnacle Studio 11 to edit HD from a Canon HV-20, but it won't work with .MOV files.
