How do you change the recording speed? I am unable to do it
with dvdrecord.

I find it must faster if I open and read the device file directly.
On solaris, that would be something like /dev/dsk/c1t6d0s0. Since
the iso file should still be around, after each burn I do something
like:
cmp /dev/dsk/c1t6d0s0 dvd_image_file.iso
Burn reliability is also very dependent on the drive itself. I bought
two Pioneer A04 at the same time. One of them never showed any
problems in a month of use, but the other could not successfully write
a single DVD-R. This is with Verbatim media. Teh faulty drive has no
problem with DVD-RW, CD-R, or CD-RW. I am eager to try recording DVD
at 1X speed with it, but I don't know how.
