Was sick of waiting for the 'good version' of Seagull Video Player to manifest itself at my local second-hand store, so just finished an Applescript application allowing the selection and playback of entire-folders of QuickTime 6 compatible videos. Each video plays, closes and opens the next all by itself - you might even say it was 'computerized' :0)
Offers Normal (alphabetized) and Random playback.
Comes with decent Read Me.
Note: The ONLY way to close the app - short of allowing it to finish playing is to force quit. Sorry, Applescript has its limits, but this is actually not too bad in practice (especially if the video currently playing is paused first).

Architecture: PPC
Tested in Mac OS 9.2.2 / QuickTime 6.0.3 on G4 PowerMac
