Hi, I am not sure, whether you have purchased something by now. But, I would recommend Powerline adapter for this purpose. I have 4 of this and one near my TV and then connected a 4 port Wi Fi Router, so that, I could connect my XBox, AC Ryan, Marantz SR5006, TATA SKY HD etc. One Powerline Adapter should connect to the ADSL Modem thru wired, and another one near the TV in the power socket. It works perfect no cabling and as well no breaks for even full HD movies! I bought TP Powerline 500MBPS for 40GBP a pair. It got very good reviews. Moreover, their support was good as well, when I had some issue setting up 4 adapters. M2C.

I'm not sure why this is not being used here extensively. How do they actually work? Do I just need to connect one with the wireless router and another one to the TV. Can I stream the movies in my hard disk to the TV in HD quality? How about the cost and is it worth buying?
