Are you talking about your tactic to hide the fact that neither DVD+R nor
DVD+RW support SAO recording?

The best recording quality and readability is caused by writing in SAO mode.

DVD+R usually does not know the size of the medium when it starts
writing and therefore writes the TOC after the data. With DVD-R and DVD-RW
and cdrecord you write in SAO mode which causes the TOC to be written first
and the data to be written later without the need to reposition the laser.

What das DVD- to offer?
