Cons: 1st unit failed 1/2 way thru a burn. 2nd unit would not recognize any blank DVD at all. 3rd unit made 1 copy then refused to make anything over 20 minutes, and would not finalize the disk. Gave up.
Summary: The hardware itself is very nice and does what it should most of the time. It's extremely fast and quite. The only trouble is that Sony's support for DVD-RW is pretty weak and doesn't play well with other RW devices (e.g. the CD-RW drive my computer came with preinstalled). It ships with NERO Burning ROM SE, which is a VERY nice piece of software - the best, in my opinion.
Cons: I bought this and it has not been compable with my system yet.I'm running Windows XP Pro. Sony was helpful on the instillation, but it has not worked right yet. The Sony software required me to delete other companies software before it would run properly
