I've been using -dvd-compat in combination with image files
and never had a problem with booting (live system image ISOs).
In "man growisofs", one of the examples explicitely reads:

	To use growisofs to write a pre-mastered ISO-image to a DVD:

	    growisofs -dvd-compat -Z /dev/dvd=image.iso

So this seems to be the correct usage...
