Ok I'm going to Purchase a DVD burner very soon and I was looking at this Panasonic because its a cheaper price then most, although I know it doesn't rip DVD-RW and that is okay I just want to make back up DVD's.....But my question is I read the specifications and it says it supports "4.7GB DVD-R General Use (write-once)"....But I know for example that 13 ghosts is over 7 Gigs....So does this mean the Panasonic DVD burner I chose will not be able to copy most larger DVD's?? PLEASE HELP!!
