That's something I've experienced too, you can't treat video files the same way as audio files.
For example if I accidentally delete a video file from the hard drive that's been used in a session, Pro Tools will ask for it even if I delete the empty video track and clean the pool or whatever the window on the right side is called. I'm pretty sure it's my lack of understanding rather than a problem with the software so I'm subscribing to this thread to see if someone knows the solution.
