I've happily used cdrecord many years on FreeBSD, admittedly only up to 7.1
on my burn host. I didnt notice anthing odd in your posting (OK
didnt look Real hard).  Maybe you were just unlucky & really did
have bad media.

Might your current working directory for myfile.iso be nsf mounted
on a slow net & cant keep up supply of data ?
(do ftp test to other host if in doubt, Ive had cases in past where
a bad electrolytic capacitor in power supply dried out, voltage dropped,
connection remained, but rate slowed)

Could it be that SCSI interrupts of writer are getting priority
over hard disc reading the source .iso ? (though OK I see
nothing else on your bus 2), not sure how priority works with mutiple busses
... anyway maybe data is from ATA not scsi disc.

If you have RW media (so it wont burn a small hole in your pocket)
Do a number of writes.

If you dont have RW media at least try a nymber of writes with -dummy

Is your machine heavily loaded or intermittently so ?

Is your processor too hot ? ..etc .. :-)

PS this posting topic would be more normal on hackers@ rather than
this multimedia@

Good luck,
Julian
