Hey dark, ive only used 2 different movies to do my hotswap (no offense to soso, but im not gonna pay $50+ for a dvd drive to backup my games when there are other methods that require 2 more steps and save me that much more money)
I use Shrek 2, or the Patriot, both are DL and are 7.8-7.9 in size...
ugh...you dont need a dvd higher then 8gb, strictly because there isnt a 360 game over 8 gigs....
every iso you ever make with exripper will be 7.3 i d beleive (least mine have been and work fine)
and dont worry about the SS/DMI/PFI crap, just get Xdvdmulleter and correct it with the online database (I fail to see how this could be considered illigal, as backing up your *own* copy is pretty much the same thing....regardless)
just some people dont wanna waste extra cash on a different burner when they dont need to..
Backed up all my games with hotswap method, works great!
