2 questions

Dear Debian CD Team,

I have two questions which I could find in neither the faq nor the
mailing list archives.

#1: what is the difference between official and unofficial CD images?
Which one should I use?
#2: I downloaded a DVD image with jigdo and tried to dd it to a DVD-RAM.
Unfortunatelly the last 30 Megs didn't fit. I assume (couldn't really
check) that DVD-RAMs are smaller than DVD+-R,RW discs.
Are there .jigdo files for DVD-RAM disks, or can I tune a .jigdo file
manually?

thanks
Andras
