Hi I just got a brand new mac OSX for christmas and am very new to this DVD thing to I tried to open a movie I downloaded it was a .mpg and when I try to open it it says software componets needed by movie could not be found. What is it talking about? Do I need to download a different player? I have quick time. I also have iDVD on the bottom of the screen. So my question is how can I play these movie on my computer? Please Help Thanks Tipsea
