Need backup software supporting multiple DVD R/W spanning

Hi all!

I've about given up on this dream of mine, but I thought I'd run it by you before I decide to throw in the towel...

I'm looking for a backup program that will support multiple DVD R/W drive-spanning. I want to take, say, a 25gig file and back it up to as many DVD's as it takes. There are PLENTY of backup programs out there that support disc-spanning (I've just finished testing at least 20 of them), but they ALL only support a SINGLE DVD drive...which means I have to manually switch media after each disc is full.
I have 5 DVD burners, and I'd like to put a blank in each and have the pgm go from one drive to the next until they're all full, at which point I'd reload them.

Before you mention NTI Backup Now! 4, which does EXACTLY what I need, I have to report that after purchasing it last year, I have YET to be able to get it to run reliably. It seems to have major problems with something else I have loaded (probably Pinnacle Studio 10, DVD Workshop, Vegas Movie Studio, etc.) so basically it was a waste of money (the TRIAL version worked great, but the full version has never worked for me)
NTI tech support is NON existent, as they have never responded to my forlorn emails.

Anyways, I thought I'd put this put there and see if anyone has heard of anything that does this multi-drive spanning...

I'm really surprised that it's such a rarity, with only NTI supporting this.
I even tried Backup Exec and Retrospect, some bigger-name players, and they don't do it either. Always just a single drive.

Thanks everyone!
