Important.png Note: The correct title of this article is cardinput table. It appears incorrectly here due to technical restrictions.

The cardinput table contains a row for each input listed in the capturecard table. It uses the videosource table as a reference. For example, a video capture card can have an RF input, an S-Video input and a composite video input. This table also stores the binding between a Video Source and an input -- if the RF input is direct analog cable and the S-video input is digital cable through a box, this is where that information will live.

The following command will re-set the channel number. Set the startchannel to something which works on your system and select the correct cardinputid for your DVB card.
