Hi,
It could be the Disks themselves, the burn speed, or even the Live File Format instead of Mastered.
Maybe the settings have changed from those you used to use. Try comparing the setup of the
other CD-R/RW's which work to the latest you burned.
Another possibility (which would also be affected by burn speed) is that the two drives have "worn"
in opposite directions of the tolerance level such that one is on the + side and the other is on the
- side when considering burn and play so the combo no longer works. If this is true then the higher
burn speeds make this even more pronounced.

Even though the Diskman is supposed to accept CD-R/RW it probably has its limits.
Why doesn't the CD player in my car play the CDs that I burn?
