I just swooped 1 up today folks, got a pioneer DVD-R/RW drive, best for the money right now, you can copy single sided dvds but not directly, you gotta rip it to your hard drive first and do other stuff. 4.7GB is the max for the dvd drives out right now.
The DVD format is @ war right now like Beta and VHS were, DVD-R/RW is most compatable with your existing dvd players while the DVD+R format is being supported by the big companies, but blank dvd prices for those are like $10 per blank dvd.
The Pioneer drive I got cost me $250 which is coo because my X-box was modded last week
Check if you homie is pushin DVD-R/RW or DVD+R/RW or even DVD-RAM which are low cost right now ($200 or less) cause they suck
