VDR
Description
The Video Disk Recorder (VDR) is a free, non-commercial project from Klaus Schmidinger to realize a digital video recorder with standard PC components. It is possible to receive, record and playback digital TV after the DVB standard. The program runs under Linux, is available as source code and lies under the GNU General Public License.

VDR also masters time shifting, that is, a broadcast can be recorded to hard disk and played back at once or after some time, but still while recording. This way one can jump over commercial or halt the playback to go to the kitchen.

If there is more than one DVB card in the system, it is possible to record more than one broadcast at a time. This is already possible with only one DVB card, but only those who are broadcasted from one transponder only.
