Hi guys, Just 2hrs have passed & I've just got a brand new Sony 40EX400. First I am a n00b in all these, consider the biggest one. I want a budget blu-ray player under 10000rs, can extend another 2-3k extra which seamlessly plays .mkv files off the USB port since i download a lot of tv shows which are 40-50mb to 400-500mb in size & also have inbuilt wireless facility to stream YouTube directly to my TV. Also I've read the sound of this TV is not great but recently when I was snooping around Big Bazaar I found this Koryo Soundbar which retails for some 7000rs. Is it worth buying it or not? Also can someone explain me what is an AV receiver.. I've been looking under the forums about various member's setups & most of them seem to have this, what is it for? plus one more thing that's getting me worried is do i need a stabilizer for my tv?
