Yeup, took more than 24 hours to run split on the file again. The net
result was 4 files, and K3B is burning it to my Double Layer DVD+R right
now. 7.5GB total space in 4 files, all less then 2GB in size each.
This is also going to take a while, so I think I'll go to bed, and look
at the results tomorrow, and see if I can get the table of contents off
the DVD after "cat"ing the files back together.
