My god, why do you have such a powerful computer?
Thats a bit overkill to play Mp3s and DVDs,
planning on playing Quake3 while driving to work?
And speed of DVD drive will play DVDs, the different speeds play DVD-roms faster, which are programs, at the same speed as a CDrom at the same speed.
I have only seen one program that was on DVDrom, and it was "Zork -Grand Inquisitator"
