Rapidshare is the most popular file hosting service in the world. But it has its own limitation so as most of file servers out there like megaupload, fileserve etc. Those limititations may include waiting time, non resumable links, non parallel downloads etc. To overcome those without premium accounts there are only two better ways.
One is to use a rapid leecher. rapid leacher is a program which when given the file adress, download adress downloads the entire file to its server and gives us an better resumable link to download that file. There are many websites out there which serve as rapidleecher, one of em is
if the above leecher doesnt work just google for other leechers
Second method is to use a software to download files.There are many softwares to do that, one of them is Rapidshare Direct Download
My personal though is JDownloader, as it supports a wide range of file hosters including Youtube
