Hi onebuck, I think the three dvds together, 32 and 64 install and source dvd
doens't fit in one double layer dvd, but 32install+source or 64+source will fit,
the final size is about 5,5GB.
Maybe this huge iso isn't available for the size of file, or maybe because
double layer dvd isn't reliable. I've heard a lot of people getting trouble
with backups in double layer dvd, but I never had such problem.
I'm from Brazil and have no credit card, so I'm figuring out how buy some
stuff at Slackware store. The End of World Mayan t-shirt is very cool
