Anyone know how to compress videos?

Ive got this video that I made of a Jack Johnson cover...Rodeo Clowns...I just need to compress the mother fucker so its under 100 mb....

the video was AVI and I made another copy thats WMV but for some reason Windows Movie Maker wont open it....neither will the Divx Converter...or even windows media player...

but it does play in my classic movie viewer and divx movie viewer....

Can anyone let me know how to compress it...or I can send the video to someone for you to compress it for me....anything would help...thanks

have you tried tubehunter? I know its aa program for downloading online videos,buti t also comes with a converter that can convert movies for ipods and zunes and stuff.
or you could try super c:

ill try that, thanks

I think if you compress your video, the qulity of your video will be reduced. So command you to have a try nidesoft video converter. with it , you could covnert your video formats into some formats which could make small space,but your videos' qulity will not be reduced.
