According to http://www.burnworld.com/dvd/primer/filesystem.htm :
"DVD-Video discs use only UDF with all required data specified by UDF
and ISO 13346 to allow playing in computer systems. They do not use
ISO 9660 at all."
Never had any problems myself with dd on DVD's, though i've only tried
it with Mac OS X disc. I use:
dd if=/dev/cdrom of=cd.iso
