We're talking about 4 - 4.5 gigs per dvd I reckon? Prolly more efficient use of storage to rip them to mpeg or avi format no? 90 Minute dvd = 4gb, 90 minute avi file = around 700mbs. Depends what you want to do really. I see that Wd have released a 2tb hard drive, should be nice & roomy in one of those fellas.
