#12 iso appears to be too large

[Ryan Hayward]

When trying to use k3b to burn an ISO from dvd95, I get the error "Data too large". When trying with growisofs, I get ":-( /dev/dvdrw: 2297888 blocks are free".

Specifically, I believe one potential remedy here would be for the user to be able to specify sizes smaller than 4.7 GB.
