Tvheadend

I am using Tvheadend 4.1-986~gfb9044c (also tried other versions, same result) on a Raspberry Pi2 with a Terratec Synergy HTC Stick and I am having trouble tuning to some Ziggo channels. Checking the mux tab, three transponders (377Mhz, 530Mhz and 682Mhz) are on status FAIL. However, they do present a number of services >0.

When tuning to one of the channels on the transponder, the log is as follows:

The channels are visible when using media portal. I have tried everything I could think of to get this solved.

Please help me!
