[bobmaldad]

Hi im having a problem but i dont know if its my ps3 or my tv or the BR disc. Ok this is whats happening, i have a LG 42" LCD 1080i 720p since 2006 and i bought a PS3 last weekend with my christmas bonus. the PS3 is working perfect with games BUT i got my first movie "WANTED" on BR, the movie had an excellent details but when comes to the parts that have a lot of movements or acction it looks like is skipping frames of the movie and look pretty bad, i dont know if you guys get my point, i double check the cables and the HDMI seems to work perfectly and i tried to change the settings on the tv and lower the sturation and contrast to see if there was a problem but it looks the same. Ok i dont know if its the BRD or the TV that doesnt support the brd but its weird cuz in the Sony Style store they play sometimes br in 720p. please somebody help me here!
