I am particularly interested in burning labelflash labels on CDR/CDRW media, but cannot find any. Is anyone aware if this will be supported?
There's no such thing as CD-R/RW Labelflash media, and I don't think there ever will be.
The Labelflash layer in a DVD is in the middle of the disc with 0.6 mm polycarbonate on both sides.
CD media is not made in this way at all, so there's no way of having a Labelflash layer in the middle of the disc - it would have to be at the top of the disc or a few microns below.
I may be proven wrong, but don't expect to ever see Labelflash CD-R media.
If you have a LightScribe capable drive, you can can get LightScribe CD-R media however.
