I've tried 4 of the 12 or so listed cable boxes in the Watch TV settings and none of them are working to control my Windows Media Center. I'm using an official Microsoft IR receiver, which I've used with at least 6 remotes without issue prior to last night's setup.
Is anyone else having any luck?
On a related note, when I was using the XO "Watch TV" app and my standard remote to control it, the screen kept freezing for 5-10 seconds. Which is new to me. I don't know if Xbox One is bugging out with the passthrough signal or if Windows Media Center doesn't like being passed through the box. I had to route the HTPC back to another input on my TV this morning so it doesn't confuse my wife, but this all seems incredibly janky as I'm running a full Microsoft stack and you'd think this would work without issue.
Once I get time later on today, I'll re-route everything again and try the other cable box sets listed and see if any of them work.
