The Plextor 24-10-40 can burn up to 95 Min.
That means that you can use a 99 Min.CD and Overburn it to 95 Min.
I always use Platinum 90 Min.CDs,i tested some for Audio(my 10 Years old JVC CD-Player plays them fine:p )
Most time i use them for DVD-copies and they play fine on my Scott838 DVD Player.
Good luck and bye...
