This is truly a great program. It has all the features of other CD/DVD burning programs and more. Instant write allows you to access the CD/DVD as a HD/floppy but unlike others it allows you to make it accessible on any computer by "closing" it. There is also a single virtual CD drive that is created. The package also includes "Expression" program, which is like a Studio 8 Lite (I actually think it may be better). And of course "Instant Copy" which is sold as a stand-alone program for coping DVDs. The interface is very clean and informative. And with a huge rebate it is very cheap- really to cheap for how much it offers.
