DVD Player Helper for Mac

From Bare Bones Software:

The DVD Player Helper performs exactly one function: it allows to use the Apple DVD Player software to watch DVD videos on a Mac on which MacsBug is installed. Beginning with the Power Mac G4 AGP (Sawtooth) machines, Apple introduced version 2.0 of the Apple DVD Player software. This version (and subsequent releases) of the Apple DVD Player do not require DVD decoding and playback hardware in order to play DVD video disks. However, at the same time, Apple introduced a limitation into the DVD player: if you have MacsBug (Apples machine-level debugger) installed, the Apple DVD Player will display an error message, and then exit.If youre a developer, and you use your machine for both software development and recreation, the error message is probably frustratingly familiar:Until now, the only way to watch DVDs using the Apple DVD Player has been to remove MacsBug from your system folder, restart the machine, watch your DVD video(s), put MacsBug back in the system folder, and restart the machine again. An inconvenient process, to be sure.
