Some DVD and Blu-Ray players will not play a burned disc until it has been finalized. Finalize the disc on your computer then see if it will play. (Finaalizing a disc means it can no longer be recorded to, by the way.)

Original dvd disc,not copy or not another countries datas disc?Same country as the DVD player was bought and formatted Disc?Most likely the disc u trying to play it is in a difference formatted of recording or finalizing data codes inbeted by some patent coded program.Tries play many more other DVD discs,should work find,than the original disc,u trying to play have protected datas or difference format and not same as of ur DVD player main programming firmware.

DVD players cannot play Blu-Ray discs. Most Blu-Ray players have DVD support, which means they can play DVDs as well as Blu-Ray. Unfortunately, the DVP3982 is not a DVD player, not a Blu-ray player, therefore it cannot support this format.

DVD players can't play Blu-Ray . You need a Blu-Ray player for that .

Follow this procedure to troubleshoot if the DVD player cannot read or play the inserted disc.

1. Ensure the inserted disc is compatible with the DVD player.IMPORTANT: Refer to the operating instructions supplied with the product for a list of compatible disc. Manuals are available online in the Manuals/Specs/Warranty section of the Sony® eSupport Web site.
   
2. Use a soft cloth to clean the disc.
3. Examine the disc for any cracks or scratches that might be interfering with playback.
4. Attempt to play another disc.NOTES:
   
   • If another disc plays in the DVD player, then the previous disc is faulty.
   • Some recordable discs may not play correctly because of the quality of the recording, the physical condition of the disc, or the characteristics of the recording device or authoring software used.
   
   
5. Remove the disc from the DVD player.
6. Turn off the DVD player.
7. Unplug the power cord of the DVD player from the AC outlet.
8. Let the DVD player remain without power for 1 minute.
9. Plug the power cord back into the AC outlet.
10. Turn on the DVD player.
11. Insert the disc into the DVD player.
12. Attempt to play the disc.

If still persists, its time for your device to get serviced.

is the dvd a store bought disc or a burnt dvd? If the disc is a store bought disc I unfortunately can't help you. But if the dvd you are trying to play is burned from dvd burner you are most likely using the wrong type of burnable dvd. There are two types of dvd's you can burn, DVD-R and DVD+R. You need to make sure which one you dvd player can play, some play one or the other, some play both. I have also heard of some older ones that can't play any type of burned disc. Hope that helps Peter

I may have bad news for you. Here's my story with the PVD4744S.

I watched over an hour of a DVD-video disc one night, no problems. The next night, I played only the intro; then the DVD player gave a message, "This type of disc cannot be played. Please insert another disc." Thereafter, I couldn't play any of several DVDs.

The manual gives little help:

My disappointment is exacerbated by the declining availability of DVD/VHS players with an RF modulator. Maybe Panasonic should create a repair kit for aging devices.
