When I use a Channels app, like on a tablet, phone, computer, or Apple TV, and I watch live TV, what resources does Channels use to send me that signal? I know it has to use the HDHomeRun tuner, of course. Is it continually writing to my hard drive while I'm watching live TV? And, if so, how long a buffer does it store on the drive?
I'm wondering about what is being used if I use Channels, on Apple TV, and leave it on, in the background, all day. I would think, if it's using a hard drive, that would wear out the drive faster (or fill it with too large a buffer of what I've been watching). I'm also wondering if this would use up or wear out any other resources I might have.
