Ok files are back online: http://sourceforge.net/projects/rsmediadevkit
If clicking on a download like doesn't work, right click on the link and choose "save target as" or "save link as". It should work.
SourceForge is still working on their site overhaul. So going to http://sourceforge.net/projects/rsmediadevkit/files/ will still show no files when the files are actually there. Hopefully they'll be fixing this soon.
