DVD Decoders and Drivers
Almost all newer computer models come with a DVD drive capable of reading or writing to DVDs. These can be formatted for data storage, audio files (similar to CDs) and video (which includes full length movies). The newer versions of Windows include an application called Windows Media Player that can playback DVDs; that is, if the correct DVD drivers are installed.
What Do DVD Decoders and DVD Drivers Do?
DVD decoder drivers are an integral part of the DVD playback system because the amount of space needed to store a movie in raw video form is more than is available on standard DVDs. When video files are stored, they are compressed using MPEG formatting. These files must be decompressed by the DVD decoder driver before playback is possible.
Getting the Correct DVD Drivers
DVD drives come from a variety of different manufacturers. The formats they use to read or write DVD data are standard across the platform, but each one is slightly different from all the rest. This means that you need the correct DVD drivers for the DVD drive you are operating.
Most DVD drivers are pre-installed on the computer system at the time of manufacture to match the DVD drive being installed with the system. In most cases, everything is compatible and all the parts work together. There are rare occasions that can lead to problems, however, that must be identified and fixed to make the components work.
Any time you put a DVD or other media into the drive, a prompt should come up asking for the action you wish to take. Sometimes, you may tell the system to play a video and instead of doing so, it gives you a message that you do not have a compatible DVD decoder driver installed. This may mean that the driver for your system has been damaged in some way. If you have recently installed a new DVD drive, you may not have the correct driver installed to operate it.
You can easily check this by opening Windows Media Player (or a compatible DVD application) and selecting the Options button on the Tools menu. There should be a DVD tab visible. If not, you do not have a compatible DVD decoder driver installed. You should be able to install the correct driver with the disk that came with the drive or by downloading it from the company website for the manufacturer.
Sometimes, the display settings on the computer may not be compatible with the DVD player or driver. If reducing the resolution on the display or setting the video acceleration to zero allows the DVD video to play, you may need a newer version of the DVD driver to operate at optimal settings.
Another potential trouble spot for DVD’s is that they are normally programmed to play only in certain regions. The variation in the encoding can prevent them from working with your system. You may be able to change the DVD region on your system through the control panel, but be warned, there is often a limit to the number of times this setting can be changed. The computer will often display a countdown when this is the case.

DirectX 9 Driver Download
DirectX enables computers that run on Windows applications to play games as it has many multi-media elements to it. There are three parts to the driver that control visual as well as audio effects. In addition, DirectX also has three dimensional possibilities for animation effects in Direct 3D. There is also DirectDraw that handles visual effects as well as DirectSound that handles audio.
Updating DirectX Drivers
There have been many versions of DirectX drivers released throughout the years. DirectX 10 is the latest and it comes with Windows Vista. For other Windows operating systems, such as XP, you can install earlier versions of this driver. You can do this by going the Start menu and typing “dxdiag” in the search box. Press enter and you will see the System” tab. You can see the version you are using by clicking System Information.
The DirectX driver is designed so that it is compatible with games that run on later versions for which they were written. You may run into problems when you are running new games on older versions of DirectX. If you show that you have versions 9.0, 9.0 a, b or c, you can find that you have incompatibility and errors occurring that will say that the dynamic link library cannot be found. You may also find that you have no sound or even come across a blank screen when running these programs.
The best option is to update your DirectX drivers so that you have the most recent version of the driver installed on your computer. This will enhance the performance of your game playing and will most likely get your games to run properly.
Driver Downloads
The latest version of DirectX for those who are not using Windows Vista is the DirectX 9.0c. This was released in November, 2008. It will work on Windows XP but not Windows 98 or ME. If you are working on those systems, the latest version of the DirectX driver is version 8.1. You cannot update the DirectX driver if you are using Windows NT.
To update DirectX drivers, you can download version 9 by going to Microsoft’s website and installing it so that it overwrites the prior version that you have in your computer. Once you install this, you will not be able to remove the diver. You should have a restore point that will enable you to revert to a working version if you find that you install the wrong version of the driver. Make sure that you are working on a version of Microsoft Windows that is genuine if you are to install driver downloads onto your computer.
You can install a driver download of DirectX 9 without saving any files. If you have any other computers on your network, you should also download drivers to each of them.
If you install DirectX 9.0c, it will download all of the files into one package. You can then update the drivers on all the machines much easier. Once you download the package of files and create a restore point, you can double click on the Direct X package and put the files into your temporary folder. After you have completed this process, you must then run DXSETUP.exe that will complete the installation process. After you are finished with this, you will then have to restart your computer.

Audio Codec ’97 Drivers
Audio Codec ’97, also known as AC97 is an audio encoding and decoding standard created by Intel Corporation in 1997. The audio controllers that incorporate AC97 controls and drivers work with many plug and play audio components. This system was replaced technology wise by Intel High Definition audio in 2004. Yet, the fact is that AC97 is still a standard that is widely used in computers of many types.
AC97 is used by the audio programs shipped with Windows XP and Vista, though it is one of the background systems that most people are unaware exist. The programs to drive the AC97 come from different sources and have been known to have some unwanted effects in a system, including unwanted sound effects when some settings are active.
One problem encountered by AC97 was caused by an automatic update released by Microsoft. The update shut down the AC97 completely for a time. This problem was fixed with a later update. However, another problem with the standard developed from the three color coded interfaces for headphones, stereo speakers, and multiple speaker systems. The speakers in a stereo system or headphones would work only as background speakers for a 3D system, meaning they would play music but no vocals. The system would have to be configured for multi speaker systems in order to work properly.
The Need to Update Drivers for AC97
Because AC97 is the standard audio controller for use in many different computers and across different platforms, boards that incorporate the standard come from a variety of different manufacturers. Each board requires its own different driver to make it interface with the system properly.
As time passes, new motherboard configurations and new boards are created that require updated drivers in order to function properly. In addition, new drivers are created from time to time to provide fixes for problems as they are learned about and reported to manufacturers. Each new driver version will have a different patch built into it for a different problem.
There are also changes in output devices, new speakers and configurations for audio equipment to hook to the computer require slightly different software interfaces to make the new equipment work with the system so that all parts function properly.
One of the features that people must work to achieve is keeping their computer up to date, with the latest version of the AC97 driver for the boards that are used and the operating system in their computer to ensure the proper function of all their audio components.
While AC97 is a standard audio controller used widely in computer equipment, there are several different versions the technology available. In order to assure proper functioning with the system in use, it is important to keep the latest versions of the drivers on the computer to ensure that all parts of the audio system work together as expected. Problems come up from time to time that require a software patch to be included in a new driver version of the driver to fix the problems, often before most people encounter them.
