======================
HARDWARE COMPATIBILITY
======================

 * Complete multi-channel (4 or 6) and SPDIF/Toslink sound device support, including 
   (but not limit to) those made by Analog Devices, Aureal, Creative, Cirrus/Crystal, 
   CMedia, ESS, Fortemedia, KCTech, Philips/VLSI, Realtek, Sigmatel, SiS, TI, Yamaha, 
   VIA and any other sound device that supports the Microsoft WAVEFORMATEXTENSIBLE 
   interface. 

   Popular sound cards supported include but not limited to:

     Creative Sound Blaster Live! 5.1 family
     Creative Sound Blaster Audigy family
     Hercules GameTheater XP 
     Philips Acoustic Edge
     Turtle Beach Santa Cruz
     VideLogic Sonic Fury

   It is recommended that you always install the latest driver from the original 
   card/device maker but not use any Windows built-in drivers in order for this function 
   to work properly. 


 * Supports video playback acceleration hardware in display chips or integrated chipsets 
   from ATI, Intel, NVidia, PowerVR, SiS, Trident and VIA/S3. Acceleration functions
   include Inverse Discrete Cosine Transform (iDCT; only for ATI), Hardware Motion 
   Compensation and Subpicture Alpha Blending units. 

   Display cards from any other vendor that provide DirectDraw overlay capability are 
   also supported.  
   
   With the newly evolved Microsoft DirectX Video Acceleration API, DVD acceleration 
   hardware can be utilized not only under Windows ME and Windows 98 but also under 
   Windows XP and Windows 2000. ASUSDVD XP is fully compliant with DirectX VA and 
   is Microsoft WHQL certified.

   If "Hardware Acceleration" is enabled, on some systems you might notice subtitles in 
   interesting colors. This is because the display driver only supports an old format 
   of Microsoft DirectX VA interface. It is recommended that you install the latest driver 
   from the original card/chip maker in order for this function to work flawlessly.

   However, if the problem still persists after using the latest driver, under Windows 2000
   or Windows XP, you will have to disable the the "Hardware Acceleration" option. Under 
   Windows ME and Windows 98, renaming the file "CLDXVA.AX" under the ASUSTek ASUSDVD XP  
   program folder will force the program to use the vendor-specific proprietary interfaces 
   and not DirectX VA. Thus, the acceleration hardware may still be utilized through this 
   method.  

 * ASUSDVD XP is fully optimized for multimedia instruction sets such as
   AMD 3D Now! Professional, Enhanced 3D Now!, 3DNow!, Intel Streaming SIMD Extensions 2
   (SSE2), SSE and MMX.

 * Compatible with new DVD-RAM, DVD-R/RW, DVD+RW or DVD-ROM/CD-RW combo drive with 
   1394, ATAPI, SCSI or Card Bus interface, as long as the drive conforms to the SFF8090 
   command set and SBP-2 (if applicable).

 * Compatible with all Socket 478, Socket 423, Socket370, Slot1, SocketA and SlotA 
   chipsets from Intel, VIA, SiS, ALi and AMD. Also compatible with Transmeta Crusoe 
   systems.
 

===============================================
GENERAL PLAYBACK PERFORMANCE AND QUALITY ISSUES
===============================================

 * To enable Dolby Headphone, SRS TruSurroundXT or Dolby Pro Logic II decoder or to play 
   DVD titles with DTS digital surround tracks, it is recommended to use a 400MHz or higher 
   processor system and at least 128MB of system RAM.

 * In 2 Speaker Mode (Audio Configuration), the "A3D/DirectSound3D" selection may have 
   weaker audio volume as compared to using "Stereo" or "Dolby Surround". This is a normal 
   occurrence.

 * Enabling video profiles like "Vivid", "Theater" or "Bright" instead of "Original" 
   consumes extra CPU power. It is also recommended to use a system running at least 
   400MHz.

 * Limitations about playing DVD files on a HDD:

   - The user should open "VIDEO_TS.IFO" (For DVD Video Format) or "VR_MANGR.IFO" (For DVD 
     Video Recording Format)to play the file set.
   - DVD Auto-Resume function will be unavailable.
   - Bookmarks may be set during initial playback but will not be available for recall when 
     playing the file set again.

 * Enabling the DMA mode of DVD-ROM drive to enhance playback performance:

   It is HIGHLY recommended to enable the DMA function of your DVD-ROM in order to 
   reduce the CPU loading when accessing DVD discs. Windows XP, Windows 2000, Windows ME, 
   Windows 98, Windows 98SE and Windows 95 OSR2 all contain built-in DMA support. 

   The ASUSTek system diagnostic utility will be automatically launched after ASUSDVD XP 
   4.0 is installed to help you activate the DMA option. However, under Windows XP it only 
   shows the DMA status of your DVD-ROM drives since Windows XP will, by default, enable DMA 
   support during its setup process.

 * Display issues:

   ASUSDVD XP supports Microsoft(tm) DirectDraw, DirectSound and DirectSound3D. It 
   is recommended to run ASUSDVD XP with the latest Microsoft(tm) DirectX Runtime 
   installed. 

   ASUSDVD XP requires the existence of the DirectDraw overlay surface for optimal
   playback performance and video quality. Almost all display cards nowadays support this 
   feature. 

   If the DirectDraw overlay surface cannot be created, ASUSDVD XP will use a slower 
   mode called the DirectDraw off-screen mode. It is either because the color depth, desktop 
   resolution or screen refresh rate is too high and leaves insufficient bandwidth to 
   sustain the creation of an overlay surface, or the display card requires the installation 
   of the latest DirectX Runtime. You can try to lower the desktop resolution, color depth 
   or refresh rate and then try again. 

   It is suggested not to run ASUSDVD XP under a 640x480 desktop resolution, since DVD-titles' 
   video resolution is higher than 640x480.


=================================
MICROSOFT (tm) DIRECTSHOW SUPPORT
=================================

 * ASUSDVD XP is Microsoft (tm) DirectShow complaint. Interactive DVD titles or games 
   can utilize ASUSDVD XP DirectShow filters to decode high-resolution MPEG-2 video clips or 
   high quality Dolby Digital audio files inherent in such titles or games.

   The newest DirectX Runtime must be installed for the filters to work properly.


================================
LIMITATIONS UNDER Windows NT 4.0
================================

 * Service Pack 5 or above must be installed for ASUSDVD XP to work properly under 
   Windows NT 4.0. 

 * Toolbar Navigator control is not available under Windows NT 4.0.
