Hello Matt,
I spoke with the sony techs several times over the last months.
1. The plugin does not exist; however, they keep telling me that sony is working on it.
2. They finally walked me through on how to view my footage on the HVR-MRC1 and import it, but it runs at the same speed as if I were viewing a tape. In other words we cannot plugin the cards into a reader and have them download instantly.
Here are the instructions on how to get your FCPX to import.
1. connect the caddy to your computer via a firewire
2. attach the MRC1 and battery to the caddy
3. click the "menu" button on your MRC1 make sure it is on "HDV"
4. you may need to click on the "cam link" button (on your MRC1) to ensure you are viewing the "CF" to computer connection/link.
5. Open your FCPX and go to file>new event
6. You should then see "import files" and "import from camera"
7. Click on the "import from camera" a window will open showing your cameras and hard drives.
8. you may need to click the play button on the MRC1 to get it to play
9. click play and then click import
For the amount of money spent on this product you would think they would have rolled out the plugin by now.
Frustrating.
