I’m normally just a lurker on this list but I am wondering if you’ve tried downloading and testing with AJA VTR Xchange to see if you can access the deck. If nothing else it might help isolate the problem to FCP.
If you don’t have it already, it’s available here:

Best of luck to you!

That was it. Thank you. Totally. I owe you a beer. ;->

With the material in question, this is in fact what I did – making a short test capture until I got all P frames. Then I knew I was good cause the cadence was completely consistent – only the location of the A frame was random.
You can also eye-ball the thing on a progressive display, counting jitter frames and looking for the cadence. You need a well lit section with lots of motion to do this.

Can’t the first A frame really fall anywhere? I’ve worked with telecine’d film supplied by clients where I was doing the IVT back to 24P when I transfered it from tape to QT. It was quickly apparent that the pulldown cadence didn’t always start on frame :00 and that I had to manually determine the cadence (which was invariant) before each transfer. (Note: the Decklink card I was using to perform the IVT allows you to set the A frame to whatever ever value you wanted.)
Possibly this was the result of a sloppy transfer. What’s the skinny?

OK I have to ask (understanding that the Io *doesn’t* do what I’m about to describe):
Won’t the image be subsampled into 4:1:1 for preview via DV? If so, why would someone want to preview that way – unless DV was going to be the final output media?
Or am I missing something entirely here?

This afternoon I took a close look at an SD-2000 system owned by one of my clients. It includes the 5.1 encoder option. What I saw was pretty radically different from my SD-1000 system.
There was but one card installed in the G3 with a single SCSI-3 connector on the back (no S/PDIF). The cable from this card was then attached to the largest of three outboard processing units which made up the system. An internal slot in this processing unit hosted the SD-2000 card itself, though all other connections with the card were obviously internal to the processing unit in which it was installled. The two other smaller units were connected directly and indirectly to the largest unit using what I think were SCSI-3 cables. These units provide input and output for AES audio (via XLR connectors) and SDI video (including monitoring capabilities) as well as 422 deck control.

If you have a key file for just the Fusion card, give that a try. That will enable authoring and possibly (depending on the software options encoded in the key) even the ability to enable CSS and Regions (Sonic charges extra for this in the Fusion systems). This is a fine authoring and proofing system – IMHO – though there’s no R/T MPEG-2/AC-3 encoding w/o the SD card.
If the SD-2000 card is really gone – that’s too bad. But you say you have the outboard 5.1 processor? It’s a rack mountable box with 6 LED meters on the front for 5.1 levels. [I can’t find a photo of it on the web.] That might be worth something by itself as an upgrade for someone with an SD-2000 and outboard 2.0 processor.

When the Sonic software is installed it includes on-line versions of the manuals. Look for a folder called “Documentation” where the Sonic applications are installed. You should find a PDF named something like “SD-2000 Encoder User Guide.” This should help you figure out the connections for the SD-2000. The Fusion card should have it’s own manual. [You can also find a tutorial here to get you started.]
As far as the keyfile goes, you might need to do some playing around with the one’s you found. The currently loaded keyfile will exist here:
/System Folder/Preferences/Sonic Preferences/
It’s called “Sonic Key.”
If all else fails, you will probably need to call Sonic.
