I have a UK bought Xbox360 which I brought with me to the US. I hooked it up and started using my gamertag I used in the UK and noticed that I didn't have Netflix etc. So I knew I couldn't change the region so I decided to play some Call of Duty Black Ops online and even though I set preferences to local I kept getting connected to UK hosts which made the game lag badly for me.
I thought that maybe because it's a UK account that the servers will still think i'm in the UK. I made this gamertag that I am currently signed in with but it has a hotmail address ending in .co.uk. However, I have Netflix etc. on the dashboard now so i'm sure this gamertag is a US region locked one. Sadly, I still get connected to UK players quite often on Black ops. Is this because my e-mail ends in .co.uk or is it because Treyarchs servers are just crap?
