How does video compression figure into this? I've seen articles that say
video compression can yield compression ratios of over 100-to-1. Does this
mean that the .6 gig CD-ROM now holds 6 gig?         

Speaking with someone at New Video last week (they are working on a DVI
board for the Mac), he told me that he expected that I could get about
100 minutes of video on a CD-ROM (using their compression).
