Both these issues would be bugs, IMO. In fact I am sure both does work
in some installations.
Have you tried debugging this using debug output of the SD at a
reasonably high level?

The DVD handler script writes its data in "slices" to the so-calles part
files. That's wjat the SD expects, and thats what the %v variable is for
- it hlds the name of the current part file.
If you use a DVD handler script that conforms to Baculas implementation,
that would not be a problem, I suppose.
Otherwise, if you want to write the files in a job-related script, you
might have to follow my suggestion to use the job id and fnd the related
volume files yourself.

Right. The SD can only commence when it has a usable volume, and that
volume has been automatically created the instance before. Now you only
have to supply the physical disk that will hold the volume.

As you use a non-standard way of handling the volumes and device, you'll
probably have to debug this yourself...
You might have better results in the end if you asked for support
getting the standard setup to work for you.
