A:AnswerSure, no problem. You could do it four ways. 1) the coax cable out from the box screwed onto the back of the tv. 2) an HDMI cable out from the box (if available) to the tv. 3) a red/white/yellow RCA cable from the box(if available) to the tv. 4) there is a Directv app in the Roku channels that you use your current Directv account info to access. Download the manual, all options are explained with diagrams.
A:AnswerYes as long as you have the Apple TV box just plug it into one of the HDMI PORTS. IT does have Roku built in so unless you want to watch something thats only on the Apple TV programing you will not need Apple Tv.
A:AnswerYou need an HD cable box that connects to the TV HDMI port. If you're connecting to the coaxial input you won't get full screen unless you set the picture to zoom.
