so i bought the slingbox pro hd from amazon used.a sling rep sent me this link to set it up. http://download.slingmedia.com/player/pc/SlingPlayer_2.0.4522_Setup-Global.exe
i have the comcast dci105com105 dta. it seems no matter what device i use in the setup, it shows a power button to click to turn the device off. my dta is always on. any help choosing the right device on or remote code that will work with the comcast dta?
