John and Eric,

Thank you both for your feedback (also valuable to the Bacula community
particularly those who are new to Bacula). There is indeed more to using
optical media than at first what meets the eye but if it is indeed true that
using optical DVD is still somewhat beta-like in a Bacula-specific context
then I am all all for pushing things forward and doing some of my own
testing and reporting back the results to the Bacula community. I'll be
using an Apple Xserve Intel machine (current version of this machine) which
supports a variety of DVD formats (read-only and read/write) but not
DVD-RAM.

Cheers,

-Hydro
