Copy Protection / Decryption

Most DVD titles, particularly Hollywood movie titles are encrypted by region code numbers to protect each region’s distribution of the title. In general, the whole world is divided into six regions and users are only allowed to playback Hollywood titles of the region they are located in. PowerDVD implements a strict decryption function allowing users to define their region code numbers and playback encrypted titles. Users may modify their region code numbers up to five times only.

Before You Begin

Some users may find the video/audio playback quality not as smooth as expected. This is probably due to the fact that the DMA (Direct Memory Access) mode of your DVD-ROM drive has not been enabled. Therefore, it is very important to make sure that you have enabled the DMA mode of your DVD-ROM drive before using PowerDVD.

If your system uses Intel chipset, such as 82440FX/LX/BX/EX or 82430FX/HX/VX/ TX, please go through the following steps to enable the DMA mode of your IDE DVD-ROM drive.

First refer to your system manual to determine whether there is an Intel chipset. For system that uses non-Intel chipset, it is recommended that you install the bus-master driver that can be found with your motherboard support CD-ROM or disk.

It is noted that, with platforms based on non-Intel chipsets, the following steps to enable the DMA mode may cause PowerDVD to work improperly on your system.

For Windows 95 OSR2 or Windows 98

2.On the Settings tab, you can see the DMA option on the Options window. Please check this option to enable DMA.

3.Reboot your system to enable the DMA mode of your DVD-ROM drive. You should be able to see that the video playback quality is improved.
