Ohhh, not a great idea to copy on the fly. I would buy a second CDRW that also plays DVD ROMs. The price is only a couple of $ more than a straight CDRW. Most CDRW has a higher recording speed on CDs than the DVD RW can do. You wrote that you are buying a DVD+R, I hope that you meant DVD RW that writes both +R and -R.
3 different OS, so yep I\'m confused.
