You can record back to Sony HDV camcorders. I do this often with the A1 and Z1 using firewire.
You must use PRINT TO VIDEO to do so.
First, make sure you captured in HDV (either 1080i50 or 1080i60).
You can only lay back in the format you captured (based on camera).
Under AUDIO/VIDEO SETTINGS:
1. Make sure the correct SEQUENCE PRESET is set to either 1080i50 or 1080i60.
2. Capture Preset: HDV
3. Device Control Preset: SONY HDV
Then select tab: AV DEVICES
On box DIFFERENT OUTPUT to Edit to Tape/PRINT TO VIDEO
select HDV (1440×1080)60i (USA) or 60i (Europe)
audio: default
Place your clip on time line, go to PRINT TO TAPE follow directions.
FCP will do some voodoo to prepare for playback.
When it is ready it will tell you to start record on your machine. Start your machine, then hit OK.
You WILL see the REC going in realtime in the Z1 viewfinder.
hope that helps.
