QVC bug on xg2. When flipping through channels, QVC randomly comes on. How to fix?

If you avoid channeling on QVC even for a second, it shouldn't happen.  At least that's how it works in my case.

In my case, I watch a lot of MSNBC   #317   QVC is on channel. # 316 and I accidently down channel once in a while.  And without fail when I do that, I have the QVC problem-otherwise never.
