A pressure indicator of an underwater camera housing has an indicator support surrounding an opening. An elastomer facing is united with the indicator support. The facing has a free region overlaying the opening. The free region has an inner surface and an outer surface. The free region is deflectable by a relative pressure differential between the inner and outer surfaces. Excessive inward excursion of the free region can be prevented by a backup.

The system of claim 11, including a user input portion that is selectively used to direct the controller to arrange the identifiers in a chosen arrangement and the controller assigns new identifiers to the portions that are indicative of the chosen arrangement. 13. The system of claim 11, including a display that selectively displays the video data responsive to the signals generated by the video player portion and that selectively displays the arrangement of the identifiers responsive to signals from the controller. 14. The system of claim 13, including a user input portion that is selectively used to communicate with the controller to responsively direct the display to display only selected portions of the arrangement. 15. The system of claim 14, wherein the user input portion is used to communicate with the controller to responsively direct the video player portion to play selected ones of the portions in a chosen sequential order. 16. The system of claim 11, wherein the arrangement of the identifiers includes a plurality of levels and the first identifier is in a first level and the second identifier is in a second level that is a sublevel of the first level. 17. The system of claim 16, wherein the video portions include a plurality of sessions, a plurality of scenes within each session and a plurality of frames within each scene and wherein the controller arranges the identifiers such that the identifiers corresponding to a beginning of each session are in the first level, the identifiers corresponding to a beginning of each scene are in the second level, each scene identifier is linked to a corresponding one of the session identifiers in the first level, the identifiers corresponding to a beginning of each frame are in a third level and each frame identifier is linked to a corresponding one of the scene identifiers in the second level. 18. The system of claim 11, wherein the storage medium is a video cassette and the identifiers include VASS pulses. 19. The system of claim 11, wherein the storage medium has a beginning and each identifier includes an indication of a location of each portion relative to the beginning of the storage medium and at least one of the identifiers includes a description indicative of content of the at least one portion. 20. The system of claim 11, wherein the video data comprises a plurality of frames and the controller determines the locations of the portions by determining a difference in a video characteristic between adjacent frames of the video data, comparing the difference to a preselected threshold and identifying locations of different portions where the determined difference is greater than the threshold. 21. A computer-readable medium having a plurality of computer-executable instructions to execute process steps for indexing a plurality of portions of video data on a sequentially accessed video storage medium for selectively viewing the portions in a chosen order, the computer-executable instructions comprising: a first program module for determining locations of the portions of the video data on the video storage medium; a second program module for assigning an identifier to the location of each portion; and a third program module for arranging the identifiers into an arrangement where at least a first one of the identifiers is related to a second one of the identifiers such that the portion corresponding to the second identifier is a component of the portion corresponding to the first identifier. 22. The computer-readable medium of claim 21, wherein the third program module includes computer instructions for arranging the identifiers into a plurality of levels, placing the first identifier into a first level and placing the second identifier into a s
