RPi Lirc problem when using dvb card

Hi guys
I have (RPi 3 + Technisat SkyStar HD USB dvb card) as my hardware package and (TVheadend 4.1.2116 + Kodi 16.1 Git:c327c53 + LibreELEC Tvh-addon v7.0.444) as my software package for watching live satellite TV channels. I run Lirc-rpi with an IR receiver to control this package with a remote control. When I see a movie from my external USB HDD (I mean when my DVB card does not work), my cheap remote works perfect, but when I want to see a satellite channel (when my DVB cart acts), that remote does not work. Why?
How can I fix this?

nobody is here !?

Hi again, problem solved
I changed my dvb card and now everything works fine! But still I don t know why? I m pretty sure my technisat dvb card is in good condition. Is it possible that the problem is the driver?
