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.

It supports most of the known formats (MPEG 1 and 2, DivX, WMV, qt-mov, Real, MP3, WAV, WMA, Ogg, VCD, and DVD), acts as an MP3 streaming server, auto-detects the various partitions on IDE, SATA, and SCSI hard disks, and auto-detects sound, video, and network cards. It supports all cards as of kernel 2.6.21. Network support can be configured in the GUI. Options are menu-driven and require no knowledge of Linux.
MPEG Audio/Video Player is a simple MPEG and AC3 player for Linux, BSD, and Windows systems. It plays MPEG transport, program, and elementary stream files.

It includes a partially working WMV/VC1 decoder capable of displaying I and P frames.
Fuse Media Centre is a full featured media application. It supports audio and video files, radio streams, RSS feeds, and Podcasts.

Fuse Media Centre can use any media engine as the backend but currently only supports GStreamer.
