    Slingbox "Video signal is not supported" error on new xfinity x1 box (sound works)


      My Slingbox worked fine on my Comcast account, then I moved and got a new box and it is no longer working.  I have the Slingbox 350 and it is hooked up to my new xfinity x1 cable box.  The sound works fine but the video says "This video signal is not supported".  Any ideas on what might be wrong or how to fix it?
