I started having the same problem before Christmas. Not only with the TSV but also newer items that the Q added to their inventory.
I thought it was because I had upgraded to El Capitan, because I didn't have an issue until after upgrading. I briefly conversed with one of the moderators and they couldn't come up with a solution but said they would pass the information on. I still feel that it is the way Q is entering the information into their system that is causing this problem.
Someone on the electronics forum suggested I download and use Firefox. I did do that. While I still use Safari as my primary browser, whenever I have a problem opening items on the Q, I go to Firefox and am able to view them.
I wish I had an answer for you. I truly feel the problem is on QVCs end.
