I can't a PC or a Mac to see it, can't get a Firestore to react to it and I can't my JVC SR-VS30 mini-DV VTR to see it either, and that is a FIRST for that deck.

Yes, I did make sure that the output was set to "DUB" (DV) made no difference.

So, does anyone have the rundown on that Firewire port on the GZHD7?

It has been a while since I used the FireWire port for download, but I believe you must shoot in 1440CBR to get a DV feed.
