[MacDV] Will DVD SP 3 burn dual layer disk externally?

[Derek Roff]

I am running DVD Studio Pro 3 under OS X.3.9, QuickTime 6.5.2.  I would 
like to upgrade, but we are in the middle of a project, and everyone warns 
against changes in mid-project.  We own Tiger and DVD SP 4, sitting in 
their boxes.

The current project is just under 6 GB.  We bought an external FireWire 
dual layer DVD burner, with a Pioneer DVR-110D mechanism.  We thought this 
would let us burn the project to a dual-layer DVD+R disc.

After choosing dual-layer in the appropriate places (we think) in DVD SP 3, 
we tried to burn the disc.  We discovered that only the internal drive (a 
Pioneer DVR 107D) was accessible/selectable.  Toast can see the drive, but 
DVD SP 3 can't or won't.

Next, we tried creating a disc image with DVD SP 3, and were successful in 
creating a .img file.  We tried to burn this to the external DVD burner 
using Toast.  Toast started the job, but aborted when it reported errors. I 
tried to burn the image using Disk Utility, and it, too, wouldn't recognize 
the external DVD drive.

Can anyone give me any guidance on this problem?

thanks,
Derek
