KatchTV is an "Internet TV" application for KDE. It makes it easy to subscribe to "TV" channels from all over the Internet in the form of podcasts, so that you can browse channels, download shows, and watch them, all from one convenient interface. It is very similar to Democracy TV, but focuses on KDE integration, using KHTMLPart and embedded players such as kaffeine. It's much faster and lighter on resources if you run a KDE desktop without GTK apps. Installation is easy as long as your distribution has PyKDE and PyQt.
SBackup is a simple backup solution intended for desktop use. It can back up any subset of files and directories. Exclusions can be defined by regular expressions.
