Thanks for using our Answers Forum. I understand that you are thinking about changing your TV provider from cable to satellite.
The Slingbox will absolutely work just as well with a satellite receiver set top box as it does with the cable box. You will have all of the same functions, access to DVR, your guide, everything. You will, of course, have to keep your internet connection, you will also have to go in and reconfigure your Slingbox to work with the new AV device, but everything else will work the same.
Hope this helps.
