What would that be necessary for?

I'd like to prevent EIT scans on IPTV devices.

In its default behaviour VDR will add transponders and channels to the channels.conf, as a result these will be searched and probably result in a match and a timer entry, even for uninteresting or undecodable channels.

The following patch might expose the necessary API for plugins to create white and/or blacklists for EIT scanning on certain devices/channels.
