They did come around - maybe around 6 months to a year ago. They suggested replacing my TIVO which I don't want to do as I have a lot of programmes recorded that I haven't had a chance to watch. Instead, they replaced my Wifi box and the problem got much much worse. It's worth pointing out, that around 2 years ago, my landline was disconnected due to a fault in the wiring outside so I'm wondering if this is a problem. It is a very frustrating problem as it buffers and stops on all catch-up and on-demand services via Tivo on my TV, be it the Netflix channel, iPlayer or Sky Cinema.
