a nice feature of closed captioning on a pc is that you can save the captions to a file for later review. the save to file field contains three controls:

    1. if checked, the enable checkbox enables saving to a file.

    2. the edit box allows you to designate a file in which the captions will be saved.

    3. the browse button accesses a standard system dialog for locating a directory and file in which the captions will be saved. when you choose a file that already exists (either by entering the file name or using the browse button), new captions are appended to whatever was previously in the file.

    you may enable saving to a file without enabling display of closed captioning on the screen; the two checkboxes are independent.
