Yousendit.com is sort of similar to megaupload, but it does generate better download speeds and allows for larger files to be tranferred.

The problem is they have a limit. For every file uploaded only 3 downloads are permitted, and then the link goes dead.

The thought was that when you upload a video, just open up the site several times at once, in different windows. Start uploading the same video into each window simultaneously. Then, when they're all done, provide each link on the forum. Whoever wants to download the file can download off any of the links. If one has already been used up the maximum of three times, just try a different one of the links.

Clearer?
