I have bought a surround sound system from samsung with bluray compatible DVD player, one of those where you receive 3 bluray disc as a bonus one being avatar. After removing my current home theatre system and installing the new one it said on the screen that Avatar can not be played due to your system requiring an upgrade, ok then great bran new outdated!!! sat in front of laptop downloading the required file took me almost 30 min place it in my bluray driver only to say not supported. Ok then lets try for a second time take a new CD R disc sat another 30 min to load for a second time only to say not supported! well well this is the very last time i will ever by samsung product even though i have 3 of their HD TV which i love. Will never ever by Samsung product again!
