Yes every single time I open the desktop client and switch to live TV, then start changing channels. After usually between 5- 10 channel changes I get that message and then a follow-on error message about the tuner.
Ok, so you may be on to something. I did literally 25 arrow / enter channel changes and it worked just fine. Then did 5 mouse changes and error message pops up. This time I copied the details in the error message box which I see does mention things about the mouse. Also if I say continue I get that weird tuner message that pops up. And no, I am not doing any recordings so that is strange that it mentions that the tuner is needed for a recording. Let me know if there is something else I can provide.
