Okay - this is where I'm confused. I'm watching tv.univision.com right now having logged into it with my Comcast/Xfinity credentials and I'm screen recording a program (using Bandicam) that aired on Monday (by just scrolling the Live TV guide back a couple days and clicking on the show). I guess that means it is playing it in On Demand mode and it is only LiveTV that is generating the error.
So here's my question - what is the best way to tell when it starts to work again so that Channels can use it? Can I assume that as soon as I'm able to play LiveTV from their website it'll be ready to add it back into Channels? I hope it doesn't take long because screen recording is not long term sustainable, but it looks like I'd have to do it as long as I don't want to miss any episodes.
