Hello everyone, First time poster so bear with me. Over the month that i have had my ps3, i have streamed various films etc via my laptop. I recently bought blade runner blu ray and it stuttered due to a dodgy laser, (i think). A friend has a blu-ray burner and has offered to back up the disc and place the file onto my laptop and my question is this... If i do this and stream the movie, will the ps3 playback be true blu-ray, or just a good hd output due to no laser being used as such? Does the blu laser need to read the disc for true blu-ray playback or is it down to codecs on the ps3 system? Any help is appreciated. I don't want to waste my friends time if it isn't blu-ray quality.
