TV Channels
Here you can manage your TV channels. For each channel the type is shown. If a channel can be received by multiple cards (like DVB-T and analogue) then all types are listed.
in the EPG tab, if you want to show the channel in the TV guide then make sure the checkbox is enabled. If its disabled it won't show up.
With the up/down controls you can specify the order of the channels, or press on the Name header to sort them by name.
Import/Export will import/export the channel list from/to an XML file. Note: the XML format used is not compatible with that used by the old My TV plugin.
The tabs at the top correspond to any groups you have set up.
