Is it not possible to use the live tv pause/playback function with cable tv? I have xfinity which I run through the live tv app on my JVC roku tv, and I was able to successfully set up my usb drive and activate it in the settings, but when I hit pause or rewind it just goes to a blank screen and nothing happens and I end up having to exit the live tv channel all together. Am I doing something wrong? thanks!
I think the answer is as simple as it is only a feature for use with "Live TV", i.e. over the air antenna broadcasts. Since the feature came out, it has worked on my set on antenna channels, and not on the Cable box. I don't believe it was ever intended to operate on a cable source.
