You can connect xbox directly to the modem using rj45 cable. You will need to order an xbox live kit from microsoft, or you can buy one in the shops at the end of March. You still play on TV although there is some widget you can buy that enables you to play on your PC (I think) You can also get a hub from NTL for £5 a month into which you connect your xbox and your PC enabling you to use both at the same time. You can also buy a router into which you can connect xbox and PC this is the cheapest solution (apart from the firt option). To play online will cost £40 a year from microsoft. One of the most popular routers is the Linksys BEFSR41 it can be bought online for about £50. There is an xbox live user forum at nthellworld.com-ntl user group where you can get additional info.
