www.dropbox.com is what I use for videos - try it out there isn't a 300mb limit and it is a popular 'CLOUD' application.
Go to www.dropbox.com and download the application.
You will have a dropobox icon on your desktop. Open the application - drag or copy your actual video file into the application - as you would on Skydrive.
When you go online to open the 'CLOUD' version your video will be there or it will be downloading - you can view it and there are numerous sharing options.
After that you can view your Dropbox from any computer by signing in.
You must have friends who have dropbox it is very big.
