I have a slingbox and have mine working. I might be able to help you if you can give me a bit more info
on your slingbox. I have the M2 box and had a lot of trouble when I switched to the Contour 2 box. They no longer
offered the 5 componet outputs on the back of their box to go from cable box to slingbox. I had to purchase
a HDMI to componet converter that also has a HDMI straight through for the TV when watching cable.
Unfortunately I would have had to replaced the Contour 2 box and go back to my previous box with the 5 componet
outputs without this adapter. My brother recently upgraded to Contour2 and had the same problem. We both had
to pay an extra expense due to this inconvenience.
In addition, the brief time I have had Contour 2 I have had more service calls then I every had with years of the old
box so I feel your pain. Maybe some day COX will offer their Watch On LIne (watch your cable channels over the internet)
offering all the channels you pay for regardless if you in your home or away. Right now they strip many channels when your not connected to your local home router. Stupid.
