Hi Brian. Glad to hear you are enjoying the new toy.
Also, "browse Tv shows" won't register but "browse televsion" will.
If a command does not register then it's most likely just a matter of spelling. Compare what Google is recognizing and how it's spelled to the spelling of your phrases. In some cases TV might have been spelled TeeVee or T.V. etc. in our default command sets because those sometimes seemed to work better with the Microsoft engine. I don't think that capitalization is important though.
...but Vox does freeze after a while. Not sure what the issue is and will post logs later. Both the tcp and vox freeze (perhaps after idle. I'll wake up and it's frozen) and have to end the task. I also use Kodi 18 RC3 and gets most of the commands but I can't get the tv guide to load.
I'm happy to look at logs, but finding the cause of freezing can be almost impossible sometimes.
The other issue with Kodi is certainly very curious. Not sure what's going on there unless there is some sort of port conflict but I can't think why a port would be involved specifically in opening the TV guide. Does it involve a device like a PVR? In any case you'll probably need to look at both VC and Kodi logs to figure that one out.
Happy New Year.
