How can I check the video chip in my PC?

Select the Settings tab - Advanced - Adapter tab.
If you are not sure, please consult with the PC or Video card manufacturer. 

Are there any DVD decoder boards recommended for playback?

No. We do not test any DVD decoder boards for DVD models. We only test DVD playback software. 

During playback, the video often pauses, or the image breaks up, or even stops playing sometimes.

Check the following, one by one.
1. Check to see if there are any scratches on the DVD-Video disc. Check to see if the disc is bent or warped.
2. Check the system requirement information for your DVD playback software. For Example;
* Does your DVD playback software support your OS?

3. Enable the DMA option for the drive.See here.
4. Reinstall the DVD playback software, just in case. 
5. Update the following drivers to the latest versions. For details, please visit the PC maker / manufacturer's website or consult them directly.
Video card driver
Sound card driver

6.  Update the firmware of the drive, if a newer version is available. 
7.  Quit other programs before playback. Deactivate Memory-Resident programs, also. 
8.  Reduce the resolution of the video. 
9. If you have installed several different DVD playback software packages on the PC, it is better to install only one software package at any one time, to avoide any unexpected problems.

After I upgrade the OS, problems often occur during playback of a DVD-Video.

Check the compatibility amoung the OS, the DVD playback software, and the video chip.
Compatibility between the DVD playback software and the video chip may depend on the OS. A certain video chip supported by Windows 98 might not supported by Windows NT/2000 for instance. 

Where can I find a DVD driver or DVD playback software?

The DVD driver will come with your video card. Latest driver may be provided by the video card manufacturer.

DVD playback software is also sold on the market as a retail product. If your unit does not come with DVD playback software, you will have to purchase DVD playback software on the market. Or please consult your distributor for further assistance.

Region Codes for DVDs

Usually each DVD video disc is assigned a specific region. The world is separated into 6 Regions. To playback a DVD disc, the region code of a drive as to match the region code of the disc. You must set the region code of the DVD drive before playing any DVD videos.
The region code of the RICOH DVD drive can be set 5 times. This limit is set by the DVD standards.
For setting the code please follow the instructions included with the DVD playback software.

ATTENTION: After you have set the region code 5 times, the region code of the drive stays the region code of your last setting, and it cannot be changed any more.
