Everyone I am going to sound dumb now but i never knew what was bluray drivers and that my ps3 had one but anyways let me get into asking what you guys want to answer

I want to know if i have a dvd would it make it sound great on a blueray driver
and if i have a bad quality movie downloaded that stinks would it make it sound and see great

last question if i burn a blu ray dvd and my friend has a dvd player he basically can not watch it like can i use that same blueray burned cd and then burn it back to my pc and then burn it again to a regular dvd this way it would work?
