DVD Troubleshooting

DVDs are identical in size to CDs (Compact Disc audio or data), but will not play in a CD drive. Double check to make sure you have a DVD drive. Most computers in the last few years have combination or super drives that play both discs. If you’re not sure, test another commercial DVD movie to see if it plays.

I’m getting a region code error

All DVDs are set with region codes to interact with the region code set by the DVD manufacturer. Computer-based DVD players used for the first time will ask you to set the code. North America is Region Code 1. Our DVDs are set to all region codes.

I can’t get to the printable materials

Some of our DVDs contain printable materials. To access these, insert the DVD into your computer, quit out of the DVD player and open the DVD icon on your desktop (for Mac) or in "My Computer" (for Windows). Open the folder "Printable_PDFs".
You will need Adobe Reader software and a DVD drive on your computer to open the files.

I’ve opened the printable materials, now my disc won’t play

Because you opened the PDF folder on the DVD, your computer may now recognize the disc as a DVD data disc and not a DVD video disc. Try opening and running the disc through your default media player. This is usually Microsoft’s Media Player or WinDVD on computers running the Windows operating system. Also check to see if your operating system and media software application are up-to-date.

Or, if the disc icon is visible in "My Computer", right mouse click over the disc icon and select "autoplay".

My DVD Player is displaying "bad disc"

If you can play other David Knox DVDs on your system, you may have a potentially "bad": disc. Look at the burned side of the disc to see if there are any spots or smudges. Wipe the DVD with a soft, lintless cloth in a circular motion, then try to play it again. If you still encounter problems please contact us at 800-822-4221 or info@davidknox.com.

My computer says it’s missing a codec

This error usually means that your software needs to be updated. Does it list the missing codec? Go to your DVD software's website and look for new versions of the player. Check for lists and download updated codecs.
