I've tried watching Clarkson and Co using my Amazon Premium service on dozens of occasions but all I ever get to watch are a couple of minutes interspersed with 10 minutes or so of buffering before the inevitable ' insufficient bandwidth' error pops up. Even watching something on BBC iPlayer involves lengthy delays and loss of sound/picture. I've allegedly got the 150mps service tho' that frequently drops off, especially at peak times. Any clues?
I'm having the same problem. Every time I watch Amazon Prime I have insufficient bandwidth. Same goes for Netflix. Youtube works OK but occasionally it buffers. I have rebooted the modem several times after which it works, but soon it resumes normal service. Considering the price we're paying I find this annoying and a waste of time chasing Virginmedia around for answers. Who is going to sort my problem?
