did you get it to work?

i got a dvbsky T980C too for dvb-t2 reception and so far the only 
drivers that have worked at all is the ones from dvbsky directly.

i was very happy when i noticed that recent kernels have support for it 
built in but unfortunately only the modules and firmware loads but then 
nothing actually works.
i use mythtv and it complains a lot about the signal, running femon also 
produces lots of errors.

so i had to switch back to kernel 4.0.4 with mediabuild from dvbsky.

if there were any other dvb-t2 card with ci support that had better 
drivers i would change right away.

one problem i have with the mediabuilt from dvbsky is that at boot the 
cam never works and i have to first tune a channel, then remove and 
reinstert the cam to get it to work.
without that nothing works.

and finally a problem i ran into when i tried mediabuilt from linuxtv.org.
fedora uses kernel modules with .ko.xz extension so when you install the 
mediabuilt modulels you get one modulename.ko and one modulename.ko.xz

before a make install from mediabuild overwrote the needed modules.
any advice on how to handle this now?
