i have this TV for a little over a month now and i love it!
especially for it's value. samsung's inbuilt media player is awesome at playing and decoding various media formats. name it and it will play without a hitch. MKVs w high bitrate, flv, wmv, mov, DTS-HD, except Dolby TRUE HD. still my only gripe is the screen's glossy finish, making it reflective. but then again, thats to be expected from a plasma, good thing i have blackout curtains in my room.
