Thanks for replying!
Just so I'm clear, you're saying that even though it says 0, not 1 or 2, after "Active Ports" under the 1394 menu in the super secret menu, you think because my firmware is 9.19 at least one if not both firewire ports are enabled. So I could hook up a PC, but not a DVD Recorder, via firewire.
And that's a bummer that the front firewire ports on dvd recorders don't support that 6412 function. Oh well, it was a nice thought.
Again, thanks for your response!
