a b I have this card: https://www.linuxtv.org/wiki/index.php/TechniSat_SkyStar_S2 and its using this driver: https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/log/?id=refs%2Ftags%2Fv4.6.4&qt=grep&q=cx24120 VDR can scan and then i can tune into the channels that have been find. When i remove VDR and install tvheadend (4.2 or 4.0) i always get while scanning the message: scan no data, failed I tried kernel 4.6 and 4.4 and both didnt change much. I reinstalled fully the system - no difference. In irc linuxstb told me to contact perexg but he was not online at the moment. I dont know what i could do to fix this problem.
