@KathyIowa I'm curious. Do you have Comcast or Cox as your cable connection? They should be able to tell you what the story is, although sometimes it depends on who you reach at their headquarters when you phone.
One Comcast representative I phoned insisted that CSPAN only had two channels although there are three, because I had watched CSPAN 3 at someone else's home who also was a Comcast customer. Could not win. Had to hang up and phone again to reach an employee who did have the correct information.
Your cable provider should have an online list of all their available channnels. Has your contract with them expired recently? If it has, the channels available to you can change and some will disappear from your personal lineup.
Typically with Comcast there is a two year contract, in my experience.
At the bottom left hand side of QVC's online program guide, by the way, there is a spot where you can type in your zip code and find out on which regular and high definition channel your cable company carries QVC.
Please let us know what you find out.
Best,
