Ok, this is really basic, but I can't for the life of me figure out how to actually schedule the DVR to record a TV show. This should be dead simple, right? I've searched the main website, and apparently this is so obvious that there isn't a how-to or step-by-step instructions that I can find.
I've successfully installed the server on my Mac Mini and set up an external hard drive as the recording directory. I just bought an HDHomeRun Prime cable box and installed my Verizon FiOS M-card. I have successfully logged into my Verizon account and all channels (including NBC, CNBC, MSNBC, etc.) are showing and I am able to watch them live. All good.
So how do I set up a Pass to record my fave news show every day at 6 PM?? I tried going to the show in the Guide, clicking on it, double-clicking on it, clicking and holding... nothing. I tried searching for the show - as the on-screen menu suggests - and the show is not found. It also does not show up in "On Later". How do you schedule a recording??
What am I missing here? I'm technically competent. I write code. I manage two WooCommerce websites. But I can't for the life of me set my DVR to record! 
Please help.
