writing double layer Dvd's

[Ric Moore]

Sure, I could Google, but I don't trust "them" as much as I do you. I'm
about to write an iso file to a double layer Dvd. I'd like to hear just
what is a good burn speed. The box sez no more than 8X. Well, what would
be better? 1X? 2X? 4X? I'd rather it not take the weekend to burn 7.4
gigs. But, these darn disks are expensive. I really don't want to make a
$4 coaster. What say you?? Any caveats? Thanks, Ric
