Don't know if the Formac Studio TVR is compatible with FCP, but you can try these steps:
Shane's Stock Answer #8:
A simple path is mac > firewire > camera or deck > rca cables > tv
Then start up your camera and tv, then open fcp.
Then go View > External video > all frames
Video playback should be Apple firewire NTSC (If you are using an NTSC set)
Audio playback should be Audio follows Video
Techinially, this should send synched video to your TV
If for some reason you can't view your timeline on your external monitor, there are a few things to try:
1) Make sure that the camera/deck is connected and powered on BEFORE you open FCP.
2) In the Final Cut Pro menu select AUDIO/VIDEO Preferences and make sure your signal is being sent out thru Firewire DV.
3) Go to the menu and select VIEW>EXTERNAL>ALL FRAMES.
4) Click in the % box above the image and select FIT TO WINDOW.
5) Go to VIEW->refresh A/V devices
6) Make sure the Log & Capture window is closed
If you want it to play in both the canvas and the external monitor you need to go to the FINAL CUT PRO menu and select AUDIO/VIDIO settings and make sure MIRROR ON DESKTOP is selected under the PLAYBACK OUTPUT section
