I have a container field formatted as interactive. On the PC if I right click and insert a video into a container field the video is stored. So I send the file to my client and he does the same thing but on a Mac 10.7.5 and sends the file back to me the video is not stored and the container reports the file as missing. But the ones i inserted are still there.
I have looked through the documentation and there is no mention of this difference between platforms.
