Did you ever solve importing files. I have same problem. I import and get No Importable Files when trying to import
Apple HDV 1080i60, 1440 x 1080 (1888 x 1062), Millions
16-bit Integer (Big Endian), Stereo, 48.000 kHz.
It’s a quicktime file that I dragged from my Firestore FS-C digital drive and no luck. It’s a .mov file and I can import any .mov file that was not on Firestore drive. Maybe I will try to put back to drive and import. Never know. If I can’t import these files Firestore becomes useless. I already upgraded my 2007 Mac Pro 2.1 with new graphics card. I did manage to install FCP X on my 2007 Mac book Pro listed as not compatible. works but slow and understandable with 3GB of memory.
