very basic question

Right - gotcha. Well Sony and their games partners have learned a lot from the DC and similar experiences and they do encrypt many of their games. However copy programs stay up with this and I've seen no reported defeats of the PrimoDVD nor CloneCD software.

The PS2 DVD game rip process is convoluted and time consuming but when you've done it once, you have a fairly straightforward repeat task with differences on the next. But time is money and I'm not sure it's that profitable to rip DVDs to a downloadable cd-size file.
