Opening quicktime container field

[nickc]

I have a database of quicktime video files (all referenced, ie not embedded). I basically want to click the container field to view the teaching videos. I have set up the container field (ref video file) as a button to open a new window and view the video file - this works fine. However the viewing size of the container in the new window is fixed. I can not find anyway to vary the dimensional size of a container field based on the known video file dimension. These files vary from smaller web based video up to HD Video (The video database has 2 fields for the x & y dimension of the file called 'videox' & videoy'. Any suggestions?
