Xawtv
xawtv is a program that allows the use of a PC for watching and recording television with either a TV tuner or a Satellite receiver card ( DVB-S). xawtv works on Unix-like operating systems, and is licensed under the GPL.
xawtv does not favour any particular desktop environment. It comes with applications which use Motif-based widgets, as well as other X11 and command line applications. It works with Video4linux and XVideo. The interface to xawtv is minimalistic.
