Tvheadend

Hello All.

I'm new to tvheadend and have problems configuring it. On my previous system I used yavdr for about 10 years. As the web GUI of tvheadend looks better to me, I decided to change to tvh. I have to PCIE DVB-S2 adapters on with each has two connections. I use three of these four connections in an unicable environment. The initial setup looked good. I could configure the adapters and everything looked good. But after an unknown amount of time three of adapters loose one line in their configuration tree. As I'm new to tvh I can't explain it, so, I attached a screenshot for my problem.
