I started having similar problems with iplayer about a week or so ago.
For a few days I could not get iplayer to work at all, it just stopped working for no reason at all and at the same time web browsing became really slow although I am still able to download files at normal speeds. I tried different browsers IE and Firefox but they were both slow, I even put together another computer with a fresh install of windows and connected straight to the cable modem without connecting to my firewall to make sure it wasnt a problem my end
Now iplayer is working sometimes but not always and browsing the net is still slow at times (not just peak times).
I havent bothered getting in touch with virgin yet because I know it will mean sitting and listening to some muppet in india telling me to reboot my computer over and over again until they realise they dont know what they are talking about and then hang up on me and all for the discount price of 25p per minute
