The main use for it would be though when i go on a ship any small video files i want to take with me could hid in the empeg.

You could create an INDEX.HTML file with links to the video files, drop it and the files onto the player's root directory, and that's all sorted then. No need to special-code Hijack for it when the capability is already there.

If you want to get fancy, grab CharcoalGray99's really nifty XML-based navigation pages, and edit those to add the links to your video files.
