I have Athlon 4800+ x2 which is basically the same processor. I am NOW not having any issues. I don't think this error has anything to do with dual core processors. I think it's the IEEE 1394 port you are using. I was having similar problems when I used my 1394 port on my Creative Audigy sound card. Now I'm not having any troubles when I use the 1394 port that is built into the motherboard. My mother board is the A8N-SLI Deluxe which is basically the same as the Deluxe so I'm sure jeh10 has the same built in 1394 port. I found this on PPro Wiki...

Daryl Lathon reports that the JVC GR-D72U requires an IEEE 1394 interface that uses the Texas Instruments (TI) chipset.
See the section Software | Capture (http://ppro.wikicities.com/wiki/Main_Page#Capture) for more information. "
Well, my camcorder is a Sony. So maybe it's a problem with the type of 1394 port. The ASUS A8N-SLI 1394 port is a Texas Instruments chipset.
So, jeh10, which 1394 port are you using? Let me know if this works. I thought something was wrong with my sound card, but now I'm thinking it's a compatability issue. Also, are you using PPro 1.5.1?
