I recently upgraded to Snow Leopard by doing a clean install, and I upgraded to FCS 3 at the same time. Everything is updated to the latest version. I've now got an issue whereby 7 or 8 times out of 10, FCP will hang indefinitely partway through loading (generally after it's finished loading the video effects) if you try and start it while a DV device is connected and switched on. As soon as you turn the device off, it carries on loading as normal. The same thing happens more often than not if you try and switch the DV device on *after* you've got FCP up and running. Sometimes restarting the Mac fixes it, sometimes it doesn't. Trashing the prefs seems to make no difference at all. It's incredibly frustrating, as you can imagine. I never had this problem using FCP 5.x or 6.x under Leopard, and I'm still using the same DV cam I did back then. Any suggestions?
