Hey guys, thanks for all your commenst and assistance.
I have tested with Spybot not loaded, same results.
As for the comments re my ISP, I fail to understand how that can be. You have a PC working and streaming, then you turn on webshield and it kills the stream, how can you even think about the ISP ?
Also we have several other devices on the same network W7 devices, tablets iphones etc, all work fine with netflix.
Conclusion that this is an AVAST! issue, another clue is when I put in the IP addresses that I can catch which Netflix is using (I have about 8 or so so far), the stream is staying on longer so it is those IP addresses which are being throttled. Surely there must be a way to detect a video stream in AVAST! and let it pass ....by the way I have same issues with iPlayer and other video streams. Maybe an AVAST technicians can explain how this works please.
Any other ideas welcome.
