DVD burning problems

[Robert Parker]

Burnt a ~4 gig iso to dvd like so:

growisofs -dvd-compat -Z /dev/hdc=mybig.iso

which is straight off the man page with relevant substitutions.

Unfortunately, it puts the iso within another iso so that when I mount 
/dev/hdc with the burnt dvd in it the content is just
'mybig.iso' instead of the internals of the original iso.

I could easily loop mount the iso and burn the directory tree as above but 
that will be useless if the iso image is intended to be bootable.

This is my first attempt at dvd burning in Linux so any advice will be 
appreciated.
