I use JDownloader to download from any hosting file (rapidshare, megaupload, etc). This software can download from any hosting file with automatic. You can check feature from this software from http://jdownloader.org/.
When I try to install this software from my system (I use ubuntu 9.10) I get error at window display from this sofware (font display is blur). This problem happen because my linux have two jdk installed. I get sun-java6-jre and openjdk-6-jre installed at my system. To resolve this problem, we must uninstall openjdk-6-jre from system.
