I have an error on all my devices connected to my Virgin Media hub 3.0 when I am accessing Netflix. I get a message saying I am using an unblocker or proxy when I try to watch certain programmes. I have contacted Netflix and they said that the problem is with the ISP. I rang Virgin today and was told there was no problem and that nothing could be done, that it was Netflix's issue. However, using a different ISP at work, I have no problems with Netflix and I am able to view the missing content, and so the problem is with Virgin Media. I haven't and I am not using proxy or an unblocker.
I have had a look and read on these forums that this is a common issue and a solution has been to send out a new hub router.
