Thanks, I never knew that.

What I have seen is that the disks seem to be blue or yellow. I assume
that is the color of the dye that gets burned. Yellow (also gold/silver)
disks work better for me in older drives.

The original question was about a Yamaha 16x read, 4x burn unit. I have
two of them and neither of them has buffer underrun protection. There was
a firmware upgrade for it, I applied it to one of them and it did not
seem to fix or break anything. :-)

The TEAC blanks I use are marked 12x-52x, but they burn fine at 1x.

I burn relatively a lot (average 1 set a month) CD's for OLD Macs (680x0 series
and pre-G3 PPC) and get good results burning them no faster the
read speed of the target drive.

For some strange reason, CD's burned on PC's using DVD burners work fine
when they are burned at any speed, athough I try to use 8x, which for
most of them is the minimum.
