I emailed you some information as to video resizing. Not sure what program you used to capture the video, since I've never played with an AIW card. Hopefully what I sent you will help.
Just for the info here though, what you copied to the hard disk is uncompressed, highest quality possible digital video. You'll need to compress it with a video encoder to drastically reduce filesizes. There's a program I use on my computer, called Fraps, that can record video of the computer game you're playing, as well as display the frames per second in one of the four corners.
http://www.fraps.com is the website for it and
http://www.fraps.com/faq.htm is the portion of the site that describes a bit more about how to take the uncompressed video and compress it for (slightly lower quality but)
DRASTIC filesize drop.
They tell you to use a program called VirtualDub (
http://www.virtualdub.org) to compress the videos. They have step-by-step instructions on the Fraps FAQ site that I have linked to above. I personally recommend the MPEG4 version 2 encoder, as it gives pretty high quality video/audio at the smallest filesizes that I have found (DivX, XviD, etc.)
