Hi Guys, I sent my laptop to apple earlier this week because I was having problems reading dual layer DVD's (The Leopard Disk and movies like The Great Escape). Anyways, I call apple to check on repairs and the apple guy tells me they replaced my drive as well as my logic board. Would they normally replace that if there was a problem with the DVD drive?? Will my processor/graphics card be the same? Do you guys think that they are changing this because of the infamous Nvidia issue?
