Thank you for the reply. Here is what was going on and how I fixed it. I had bought and installed a new copy of FCP right out of the box on my even newer Mac Book Pro which was running the very latest OS 10.5.2 and Quick Time – I had just run software update and installed everything. When I went to “About Final Cut Pro” it said Version 6.0.2. But, when I went to the A/V settings, it only showed xdcam hd, no xdcam ex. So, after much puzzlement, I finally went to the Final Cut support/download/updates page at Apple. You have to log in with both your Apple id and a FCP serial number. Then, after logging in, I ran Software Update again. Then it showed all these FCP updates to download and install, which I did. Now, everything seems to work fine. So apparently, Apple changed FCP slightly after they released the retail version I got, but they didn’t assign a new version number. So, what I got in my retail package was not the “real” most up to date 6.0.2, but I couldn’t tell that just by looking at the version number. I suppose this has happened to others, but they may not notice it if they are not trying to work with xdcam ex.
