It is recommended that you install the latest driver from the original card/device maker, not a Windows built-in driver, in order for multi-channel output to work properly.

PowerDVD 7 supports Microsoft DirectX Video Acceleration (DXVA) in display chips or integrated chipsets from ATI, Intel, NVidia, SiS, and VIA/S3. Acceleration functions include Inverse Discrete Cosine Transform, Hardware Motion Compensation and Subpicture Alpha Blending units.

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

PowerDVD 7 is fully optimized for multimedia instruction sets, such as AMD 3D Now! Professional, Enhanced 3D Now!, 3DNow!, Intel Streaming SIMD Extensions 2 (SSE2), SSE, MMX, and the Hyper-Threading technology.

PowerDVD 7 is compatible with new DVD-RAM, DVD-R/RW, DVD+RW, DVD-Multi, DVD-Dual or DVD-ROM/CD-RW combo drives with IEEE 1394, USB 2.0, ATAPI, SCSI or CardBus interface, as long as the drive conforms to the SFF8090 command set and SBP-2 (if applicable).

PowerDVD 7 is compatible with all Centrino, Socket 478, Socket 423, Socket 370, Slot 1, Socket A and Slot A chipsets from Intel, VIA, SiS, ALi, NVIDIA, and AMD. Also compatible with Transmeta Crusoe systems.

General Playback Performance and Quality Issues
Enabling video color profiles such as "Vivid", "Theater" or "Bright" (instead of "Original") consumes extra CPU power. It is recommended that you use a system running at least 400MHz in order to use these color profiles.

To enable audio effects such as Dolby Headphone, Dolby Virtual Speaker, SRS, CLMEI-2, DSP, and Dolby Pro Logic IIx decoder, or to play DVD titles with DTS digital surround tracks, it is recommended that you use a 400MHz or higher processor system and have at least 128MB of system RAM.

External subtitle loading: For loading external subtitles, you should name the subtitle file with the same file name as the playback video file.

DMA Mode:
It is HIGHLY recommended that you enable the DMA function of your DVD-ROM in order to reduce CPU loading when accessing DVDs. Windows XP, Windows 2000 and Windows ME all contain built-in DMA support. To enable the DMA setting, open the Control Panel, double-click System, then click the Hardware tab. Click the Device Manager button, then open the IDE/ATAPI controllers option. Double-click Secondary IDE Channel, then click the Advanced Settings tab. In the Transfer Mode drop-down box, choose DMA if available.

The CyberLink system diagnostics utility launches automatically after PowerDVD 7 is installed to help you activate the DMA option. However, only Windows XP shows the DMA status of your DVD-ROM drives since Windows XP enables DMA support during its setup process by default.

Display Issues:
To ensure that PowerDVD works properly, please install DirectX version 8.1 or higher.

PowerDVD 7 requires the DirectDraw overlay surface for optimal playback performance and video quality. Almost all current display cards support this feature. If the DirectDraw overlay surface cannot be created, PowerDVD 7 will use a slower mode called the DirectDraw off-screen mode. The reasons why the DirectDraw overlay surface cannot be created can be because the color depth, desktop resolution, or the screen refresh rate is too high, leaving insufficient bandwidth to sustain the creation of an overlay surface, or else the display card requires the installation of the latest DirectX Runtime. If the DirectDraw overlay surface cannot be created, try lowering the desktop resolution, color depth, or refresh rate, then try again.
