I have S268 on my Joey with S217 on my Hopper. I was playing around with settings on my Joey and the TV hooked to it last night and happened to click on the PTAT icon on the Joey Menu screen. To my surprise it was asking if I wanted to enable PTAT there (it already is enabled on the Hopper) and I just cancelled out of it. What does that screen do on the Joey? I would imagine nothing since there is no HD or tuners on it, but it was odd to see that option on the menu there.
