Hi Milton, 

Are any of the PGR cameras capable of the FW800 data transfer speed and is this a significant advantage? I just started using a FW800 back-up hard drive and have been loving the speed compared to FW400. Took me a a couple of months to remember that I have this port on the new laptop!

just wondering...

I was looking at the specs for the PGR dragonfly cameras the other day - it appears they use the Firewire 800 bus for data transfer. Does the Flea as well?

Don't worry about whether it's FireWire 400 or FireWire 800. PGR supplies a FireWire 400 to 800 cable (it has a FW 800 plug on one end, FireWire 400 on the other) and Astro IIDC works perfectly fine with it. Astro IIDC will detect what speed interface it's connected with and will adjust itself internally for the available band bandwidth (the code for this is pretty ugly).

As a Matter of fact, I no longer use a FireWire hub to utilize 2 cameras. I use the FW400 to FW800 cable to attach a Mono FW400 camera to the FW800 port on my G4 LapTop for guiding and attach the early model Flea FW400 camera with a FW400 cable. It all works fine.

HTH..
