#1 - I have never used the Windows movie maker but my guess is that your export settings are really high. Check to your frames per second (15 recommended) and your image size (4:3 ration, 320x240 is good) also your sound settings (mono and mid range) and if you want smaller files, then tone it down. I use Adobe Premiere 6.0 so I am just giving your the setting options info from my clips - my final product is a wmv because of the file size and ability to stream rather than having to wait till it is all downloaded.

#2 - send superjens an email, HE (oops) has room for pix and video and is glad to help out. He also has FTP access to it - pretty easy!

Good luck.
