A typical DVD disk will hold up to 4.7 gigs of data, which is about seven times the capacity of a regular CD disk. This unit, like all others, is backwardly compatible to even single speed audio CDs. Windows 98 and NT 5.0 will provide full support. It couldn't be simpler to install. Just remember, SCSI can be easy to install, but follow instructions carefully.
Instructions are minimal, since there is little to the setup.
I did have a few questions, which were answered quickly by Pioneer's technical support staff. A little of the technical stuff, then off to what I actually observed. The unit will read all the common formats from a single speed audio CD to the newest single, dual layer disk, but not a writeable or recordable disk. That's another story. That is quite good since the test bed was the minimum recommended - a Pentium 133.
