2 tuners with 2 feeds need to be setup as Simple and Single with both listing 28.2.
Because you only have 1 working feed you cant access other channel = greyed out.
The box only needs to be scanned once and find channels.
AutobouquetMaker setup to give you bouquets.
Epg setup for usb or hdd saving NOT INTERNAL FLASH.
When abm is rerun it updates the bouquets but on the second page there should be one for user to use as is not affected with a daily rescan.
