Anyone else have a problem with Netflix?

[Ashimar]

on my pc.... the window in which i use Netflix freezes when i try to watch anything, it doesn't freeze the whole browser, just the individual tab/window that its running in. i did some search on the forums and it said try uninstall Silverlight and reinstalling it. It also said close all unnecessary programs, clearing internet history, restarting PC, and trying different browsers such as IE and Chrome ( I use Firefox )

i've tried all these and i still can't get it to work. Anyone know of a possible fix
before i cancel my netflix subscription? thanks.
