Since you're using Premiere (on a PC, I assume), the cheapest way to do this
would be to find someone with a D9 deck and bring along a miniDV camcorder
(and several tapes) that's capable of analog input (most are but not all so
make sure). Hook the composite out of the D9 deck (or Y/C if it has it) and
the audio (through matching transformers) to the analog ins of the miniDV
camcorder, hit play and play/record and you're all set. The drawback to all
of this is that you're going from a pristine 4:2:2 signal to a 4:1:1. As
Bill said though, you're starting with a much higher quality signal so it
won't be that bad :-)

Your other option is, after you do find a D9 deck, to rent a Sony DSR45.
It's a DVCAM deck that will also record in miniDV format. The beauty of this
deck is that it has:
component, composite, S-video ins & outs;
four channel independent audio In/OUT with XLR connectors for audio OUT;
i.LINK(firewire) interface for simultaneous transfer of audio, video, and
command signals;
RS-422A remote control interface;
RS-232C interface for basic control from a PC;
LANC and Control S interface;
Time code IN/OUT;
Time code/User bit preset;
Time code IN through DV IN .
With this deck, even though the end signal is still 4:1:1, you'll get a much
cleaner transfer, especially if you go component.

There's a JVC DV-500 camcorder forum at
http://fastforwardclub.com/v-web/bulletin/bb/viewforum.php?f=400
I know that a few users there still have D9 decks. You could try posting a
question there to see if anyone has one for rent. Or, if you're close to
the Detroit, MI area, I know a local guy who still has a (rarely used) deck.

Mike
