Hello, I have just recently purchased a macbook 2.16 GHz, with 120 Gb hard drive, 1GB ram and I have a few questions regarding it. 1. Is it normal for my macbook to reach temperatures of 60 - 70 degrees Celsius while watching online videos on youtube and stuff like that? 2. How long does it take to burn a DVD using iDVD? And say the videos inside the DVD were an hour long altogether. 3. When I insert a cd into the cd drive, it makes this rather loud noise when taking it in and it sounds like the drive is hitting something. I don't know exactly but yeah. Is that normal? Other than that, the drive performs well. Please reply back, Thank you!
