unfortunatly i think the majority of your problem is with your provider.
i know its all virgin v Bt, but. many of my friends have gone back to bt only after a few months of experiencing the lack of quality that virgin could offer.
line quality is of the up most importance to me, as i am a senior admin for a gaming community. so i need my internet to be reliable.
the above test was from this computer i use daily. and whilst IRC, Steam, and TF2 are running. as you can see it has not impacted the results any.
my advice, is if you can switch, switch to BT. it would be the best thing you can every do

please bear in mind, if your not having troubles with your line, then you will prob be fine for the foreseeable future. but if you are experiencing continuing problems, then i would seriously consider switching
