I am going to buy a 40" lcd (either Samsung 40B650 or Sony 40V550 or LG 42LH50) in coming weeks. Currently i'm having a cable connection for my tv viewing.I'm attracted to airtel iptv services (leaving behind channel change delay problem). So, basically i'm worried about how it will look on a 40" LCD compared to Airtel DTH/Tata Sky. I've searched for it alot but can't find anything about it. Even any dealer doesn't keep iptv for testing/reviewing.What do you people say about Airtel IPTV oicture quality on this bigger screen than usual?
