How can we enable HW Compression on an LTO2 drive?

We have had an upgrade to our ancient drive carousel through a donation.  Although we are still not where I'd like to be hardware wise, the Fastor 2 we were given is much more reliable than the old Qualstar we have.

Anyway, the drive in the Fastor is an HP Ultrium 2, LTO-2 drive.  It actually came from my previous employer and I am very familiar with it's operation.  At the old job, this jukebox was used with three different backup packages (at different times) and all three were able to enable hardware compression through the options/settings of the drive in the software.  With the HW compression, we were able to get anywhere from 1.5:1 to nearly 2:1 compression allowing us to get 300-nearly 400 GB on each tape.

I am using the built-in drivers in Networker 7.6.2 and have not been able to figure out how to enable HW compression for this drive.  I did a chat session with Tech support and he told me the only way to do compression was to use the "NT with Compression Directives" in the client.  I tried that last night and it looks like it may have done some very minor compression (maybe 1.1:1)

It seems like such a waste to only use half the capabilities of this LTO-2 drive due to, what appears to be, the limitations of Networker.

Oops.  The backup server is running Windows Server 2003 Standard Edition.

Anybody know a way to make this happen?  Or am I stuck and should start looking for new backup software?
