Went and got my Cox cable card and their tuner box. Hooked it up and got it working and I get less watchable channels than I did without cable card? It only tunes in 39 channels and only 19 are watchable without drm which are my local channels. I only have Cox Essentials package but I should get all my channels in HD plus some extras as stated on the Cox website with a cable box or cable card. What the hell is going on? Thought the cable card was the cure for watching all these channels in HD? There is some type of filter in the box but no explanation for it in English! Really sucks when I can actually watch more channels without the card!
