I use 'hidemyass' as a proxy as most sites are now blocked on Virgin Media but that site works well.
You do NEED to start from the beginning in this series though. It's brilliant.
You could possibly even use hidemyass and go on 'projectfreetv' to watch it but I haven't used that site in a long time.
I highly recommend employing http://www.vpnmaster.org to unblock web-sites. I am using their services for more than 2 years without difficulties.
My spouse and i suggest making use of VPNPower to be able to unblock sites. I have been using them since four years. http://www.vpnpower.net
you must watch it from the first episode to understand what's going on.
What I mean by this is could I watch TD from Season 1 Episode 4 onwards and understand what's going on? I say this because I want to see what the fuss is about, however my online catch up TV library (NowTV) has just episode 4 onwards.
