My receiver came with twin satellite tuners, and twin terrestrial tv tuners so I could record 3 programs and watch another program . This has worked well , but more recently ince I flashed the receiver with the latest image , the receiver doesn't see the twin TV tuners, and will only record 1 program if we want to watch another.
I have checked the cable connections, unplugged and replugged , also checked the settings so that the local tv transmitter is selected, it wasn't after the initial image upgrade.
I don't know what else to do or check in the tuner settings.
Help please
