I have a Brand new MacBook Pro and i have been trying to burn DVD movies onto DVD DL blanks and it does not seem to like the memorex brand. My question is what might be the issue or if the Mac does not like certain types of DVD DL disc's. When i do try to burn the DVD it comes up with an error saying hardware error and it will not make it through the lead in for the movie. Also i have tried burning a movie once before on a Vetbatim DVD DL and also on a Sony DVD and it works fine. So i am just trying to figure out if i have messed up my MBP or if it is just the type of disc. Thank you.
