I was just forced to replace my Motorola cable box with the new Samsung SX022ANM X1 cable box. In reconfiguring my M1 Slingbox I can't find that particular cable box listed as an option. Is there one listed that will work? or is the M1 even compatible with this cable box. I know I'll need an HDMI splitter. Will upgrading to one of the later Slingboxes work?
