At best, it's going to be the smaller of the drive capability and the
media capability. Sometimes you will have to reduce the speed further to
get the CD to be readable on older drives. It depends.

You may just have to experiment. They could be anything from 1x to 56x,
although I suspect they are on the lower end, given the purchase date. :-)

What ever they are they are missing some optional information. Here's the
atip from one of my CD-RWs:

ATIP info from disk:
Indicated writing power: 3
Reference speed: 6
Is not unrestricted
Is erasable
Disk sub type: High speed Rewritable (CAV) media (1)
ATIP start of lead in: -11625 (97:27/00)
ATIP start of lead out: 333750 (74:12/00)
speed low: 4 speed high: 8
power mult factor: 1 5
recommended erase/write power: 5
A2 values: 26 B2 4A

Note that 6x is the recommended speed and that between 4x and 8x is
allowed.

I recommend you start at 4x and work your way up and down.

This is done with the mkisofs -V option. You can also set the volume name
with with VOLI environment variable. This is handy because it keeps the
mkisofs command line shorter.

Keep in mind that RSJ creates an ISO for you, under the covers. Many of
the things it does apply to making an ISO. They are functions done my
mkisofs, not cdrecord.

HTH,
