Apple DVD Player
Both Rage128 and RADEON AGP/ PCI products fully support Apple DVD Player version 2.2+. You do not specifically require an AGP video card. Version 2.x of Apple DVD Player will not run on older machines (it will run on any AGP G4 and some iMac, Powerbook and iBook models).
PowerMac G3/ PCI G4: Older systems supporting DVD must use Apple DVD Player 1.3. This hardware-based DVD Player will only run with the built-in DVD Decoding hardware installed in your machine. You must have a monitor connected to your built-in display hardware and this device should be the startup screen (Happy Mac icon in Monitors Control Panel). For Blue and White G3 or PCI-Only G4, the Rage128 with Hardware DVD module must remain in its default slot (PCI-66). For further information on Apple's DVD Player 1.3, please see Apple's web site and Knowledge Base (Tech Info Library).
Apple DVD Player 2.7 is the latest version shipping on new machines as of this release. In order to provide maximum compatibility, you should run the latest version available for your computer. See Apple's web site,
http://www.apple.com, for any updates.
Adaptive De-Interlacing for DVD Playback
The de-interlacing feature may be enabled from the ATI Config Menu in your menu bar. It is compatible with Apple DVD Player 2.x
The feature is intended for use with interlaced DVD content (often material that was originally shot on video, such as TV programming, or deleted scenes and documentaries included on many DVD titles as extras). Turning it on while watching non-interlaced movies may slightly degrade certain elements, such as static text displays. An interlaced source can easily be identified on a monitor; you will be able to see horizontal striping (a shutter effect) in the video (easiest to see with fast moving subjects and high contrast areas).
The feature defaults to OFF when you restart your computer. It applies to all suported ATI cards (Radeon) installed in the system.
