Advertisements I finally got a letter the other day from Cox stating that they moving to SDV and that Tuning Adapters are now available. I went in to my local Cox office and they had no idea what I was talking about so I called the number listed in the letter. They really had no idea either. The letter clearly states that they will mail me one at no charge but they representative on the phone wasn't sure how to get me one. She's looking into it and is supposed to call me back. I'm not holding my breath. I guess it's just something I have to put up with for not using a Cox DVR.
