Tuner config on solo2

Hi, I was setting up 2 vu solo2 boxes for 2 seperate friends, both on vix as that's what I use on my duo, I set tuner A as single 28.2 and tuner B equal to tuner A. As soon as instart recording all channels go blank as if only 1 tuner working? I tried setting both tuners to simple, single 28.2. Tried setting tuner B to loop through tuner A. I checked I was getting a feed from both cables and I checked individual timers. All worked fine. Channels 1 to 5 always worked when recording but my paid channels would not work when recording.

It's latest vix image, I set both to simple, single 28.2 but same thing happens,
