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.

KutttPech is a MPEG-player in Java, capable of playing MPEG-1 within your browser without downloading any irritating plug-in. It is specialized in handling live MPEG streams, but can play files just as easely. It plays Layer 2 audio on most browsers with java 1.1/1.2 and on all browsers with 1.3. It can cut P-FRAMES and B-FRAMES if the machine is too slow to handle them, so as to maintain a small lag. It can run outside a browser as an application and is reasonably fast.
