I can only assume so as both show as available on the feeds.
This is the first time I've tried to use these tuners on the 4k as I'm re-arranging tuners to make full use of both FBC tuners so I've no idea if they even worked on the previous ViX.
I see you have a Sundtek S2 on your 4k, perhaps you can advise on the settings for that, I also have that tuner and I've tried to use that on a fairly complex setup that involves a DiseqC switch and a motorised dish but it doesn't work.
I've installed the control centre and updated drivers but it's not working for my setup, perhaps it's fine for a single LNB but not a more complex setup ?
