User Feedback :: DVD while in ram?

I just ordered a cd last night, just one question, is there anyway that you could play dvd's, while running in the ram? I didn't really check to see if it was came with any dvd playback ability, just wondering if any of you know? thanks.

DSL off the cd doesn't have any software to support DVD playback, but if you do a hd install, you can apt-get mplayer and it plays DVDs
