Hi I have an M1 slingbox. The instructions indicate I should plug the video cables (green, red and blue) into my cable box but my cable box doesn't have a space to plug this type of cable. I have xfinity X1 and a samsung xg2v2 box top. This Samsung box top has an hdmi port, and an audio port but not the video port I am instructed to install the cables into. What do I do if there isn't a video input for me to plus the M1 cables into.
