All you guys who've made videos and put them on the web - how large were they?

I've just had my Sony digital8 back from repair and made a very quick and nasty video of me shaving my head. It's 6 minutes long (roughly) and the best part of 200Mb in size!

I've got something called Pixela that came with the camcorder, and it lets you edit etc the video. But the only format it lets me save into is MPEG-1. Would being able to convert it into another format like WMV make it's size smaller? Or is there something I should have done on the camcorder? Or is 200Mb nothing to worry about?

Thanks for any help.

James.
