I just got a new laptop that is way better then my old laptop. I re installed everything on my new laptop and now when I burn the same files I burned on my older laptop they take forever. On my old laptop they took 20 min tops. Now for some reason it's taking 2 hours to burn a 4 gig iso file. Anyone got any ideas on how to fix this? I am running windows vista 64 bit with 4 gigs of ram my older laptop was windows vista 32bit with 3 gigs and a slower processor. What do I need to do to fix this?
