Many times when you buy a computer, you have various options you can add/subtract. I would guess that having a DVD burner vs. CD burner was one of the options.

You may try using ftp to transfer the files, if that is an option. Or, if the computers are on the same network, you can do a direct transfer over ethernet. You can also connect them via firewire, if they both have that capability. Depending on the size of the files, burning as data to CDs is also an option.
