I am having the same issue. We have the Sony M25U deck and the footage was shot 720p. The manual says Sony can only play 1080i out the firewire and HDMI outputs. That might be my issue. I was able to take the component outputs as standard def downconverting to DVCAM….I used the firewire for machine control.
I have tried this deck on a PC with Avid Xpress Pro 5.6.4 and FCP 5.1.2 on a G4 dual 1 gig and a G5 dual 2.7. this is really frustrating. The Sony manual is not very helpful really. I can see the footage just fine in the LCD display on the deck and on the component outputs. Just not through firewire. If you hare having trouble with a camcorder as your deck then I am really stumped.
One more thing, up in the FCP menu I believe there is a pulldown that says “Easy Setups” and there you will find a way to launch a “special” log/capture window that seems to be only for HDV etc. It has a different look to it, than when you launch the capture window. Try the HDV one and see if that gets the signal going.
I am curious if you ever get video via firewire and what you did to make it happen.
