I have my code working for dvb scanning just fine in dvbsections and dvbchannel, I just been busy
of recent and have't had enough time to decipher videosource.cpp to add the Transport/Channel
editor.  Is anyone intested in helping me to add this in rather than use all these scanning import
shell scripts?
