WTF with Wodim - CD Burning?

[Steve Holmes]

I have a setup here which has always worked for me in the past where I
could use genisofs to build an ISO image and that still works great.
But alas wodim is another story.  I always used in the past up to
about a year ago with no problems.  Now I get errors that cannot find
any devices.  I will add a script listing to the bottom of this
message when I'm through.

I'm using a 3.5 kernel on Arch Linux and this is an HP laptop with a
typical CD burner. internal.  It has been defined as /dev/sr0 in the
past and actually, CD's and DVD's read fine in this device right now.
So, what could be missing here?

For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.
