Input devices

As Data sources for video and TV VDR can use:

DVB cards, either DVB-T, DVB-C or DVB-S, each of them either as budget card without MPEG-Decoder or Fullfeatured DVB card with MPEG-Decoder (the latter therefore usually being output devices as well).
analogue TV cards with MPEG encoder like Hauppauge PVR 250 or PVR 350, either PCI(preferred) or USB
analogue TV cards without MPEG encoder with Booktree BT848/878
the data stream of another VDR which works as a server
