It must have DVD capabilities ? Well, I dunno..if your planning to copy DVD's; useing SmartRipper, then DVD Shrink.. yeah; you would need a DVD Burner as well.
Working with Video like that takes at least 10 gigs for the rip, then probably another 5-7 gigs for the working space..it just depends on what the computer is going to be used for. I know people who collect movies on their hard drive; so they've the largest hard drive that they can afford..it really just depends on what you're planning to do.
Of course, a fast processor is mandatory for video..but hey, I've got a Pentium III 500 processor, with 392 megs of RAM and IF I only watch DVD's on my computer..the video is perfect. No problems at all. Just make sure that you load up on memory.
But thanks for the advice-
