 - EIT scanning functionality can be disabled for all IPTV channels by applying
   the "disable_eitscan" patch to the VDR.
 
-- Source address validation can be enabled for UDP protocol separated by 
-  adding the source address after a ';' character: "U=239.192.0.1;239.192.0.2"
-
 - Section id and pid scanners should be disabled after the correct data is
   found. This can be made via VDR's channel editor.
