Importing videos into CERTAIN projects

Hey all,
I’m using latest versions of everything on Mac (irrelevant here)…
My problem is that I CAN import a certain video file into a certain project A (using File/Import). No problem. No sweat. Now if I open another project B and try to import THE SAME VIDEO FILE, Cubase doesn’t do anything (it accepts the command but nothing happens). I tried many things, relaunching Cubase, etc and I always get the same result: I can import the video file into Project A, but not into project B. I’m curious to know if anyone has seen this problem before.

Same thing just happened to me. Did you get this figured out?

I’m afraid I completely forgot about this. I probably figured a workaround, but I can’t seem to remember which one… Sorry…
Maybe it had to do with the file format (video…audio…container?) and the project setup ? If you do find a solution, please post it here. It could help someone.
