could use winrar to split the ISOs into two 4.5gb .rar files.
but since you got the DL drive now its not really relavent.
$9.99 is a good price for a new, high speed DL drive and worth getting even if you don't need one.
Changing the media should be sufficient to get it to work (i.e., changing to DVD9, ISo is just a format)
dude, if you're just burning the iso to mount on the other computer, why not just split the iso in half, so you can use single layer discs........
you're goofy, man
