One question for the Lebitbit servers... is there a safe way to go above 50KBS? I do not speak said language so I go the "slowest" route possible to avoid any issues due to my lack of understanding. Some of the Lebitbit servers want to take 22hrs + to DL a vid.
You always have to become a member on those sites so you have to pay for fast download access.. I took filesonic, 9 dollar per month pretty cheap and much stuff is hosted there..
There's no real way around the limit except purchasing a premium membership. However if you use a download manager such as Jdownloader (http://jdownloader.org/) for example, Letitbit allows resumable downloading. So you can just download a bit at a time whenever your computer is on. Works great for me.
Although there seems to be a new protocol at Letitbit since a few days that Jdownloader can't yet handle. But the community is apparently already hard at work to find a fix.
So if download managers aren't an option for you, you might also try searching for the filename on google and see if it's hosted somewhere else as well.
