In this release I added the READ DVD STRUCTURE command, as well as one kind of structure information, the Physical structure.
I also updated the ISO Burner utility to not check to see if the Next Writable Address field is valid, which is necessary for DVDs. So if you're CD is not writable, you might not get as nice an error message. However, you can now burn DVDs from ISOs (no support yet for multisession discs, however, in the utility).
Please always take a look at previous releases for more information.
