I'm not really answering your question, but how's your experience playing online? It seems that there would be a lot of delays and frame freezing.

Yes, I played Xbox Live yesterday, on airtel 256.It was laggy. There was at least a second delay between what I pressed on the controller and for it to respond on the screen.

the experience is excellent when u play with fellow indians it also depends on the game though and one more thing i was playing live yesterday i somehow figured it out but now it seems i can login to live wtf it gives me an mtu error is it something sify has done to my connection somebody heeeeelp
