Advertisements Having some issues with my m-card in my THD which are very similar to the failures I had originally with my S-cards in my Series 3 back in October 2006. The m-cards seems to lose authorization (or equivalent) about every day or so. This is apparent by losing all the digital channels. Going into the diagnostics screen gives an error about being unable to display some HTML Page. It basically says it can't locate the page. Popping the card out and back in fixes it, but it is aggravating. Anyone else seeing similar problems? It is a Scientific Atlanta m-card. Cablevision of Rockland.
