There is QVC and QVC Plus. I have Time Warner Cable and QVC Plus is on 481. The Plus shows QVC programming that was on earlier. Usually 3 hrs earlier. For instance, today Issac's show comes on at 10pm ET on the regular QVC channel but QVC Plus will have on that same show at 1am ET Tuesday morning.
I've heard that QVC Plus does some original programming that doesn't appear on QVC but I don't watch that enough to verify. I have watched QVC Plus, mainly on Saturday so I can watch AM Style later as I am not usually up when it starts. It's another way to watch a show you may have missed earlier.
I actually get 3 QVC channels on Time Warner - 22 and 480 (non-HD), 481 QVC Plus
