Cablevision Intermittent Video Issue via HDMI

[Pfish68]

I had the exact same issue about 6months back, was right around the time that IO came out with there automatic upscaling meaning if a channel was aviable in hd the box would show it in hd didnt have to be on specific hd channel. After swapping 4 diffrent HDMI cables of various brands monster momo price and one that came with my direct tv setup i contacted cable they said to try running it directly to the tv which i did still had issue. They sent out two techs one of which the descibed as a master tech, after 4 hours and 3 different boxes the issue still persisted, there final answer was and i quote "cablevision boxes are not compatible with hdmi cables" they hooked up the compenent cables and left. needless to say I am now a happy customer of FIOS
