Zenith DVD Player--DVB410/ZND400

It's possible that the DVD you are trying to play was manufactured for a different region than the one your DVD player is set to. DVD players are designed to play DVDs that are encoded for a specific region or regions. For example, a DVD player that is set to Region 1 will only play DVDs that are encoded for Region 1.
You can check the region code of your DVD player by looking at the back of the player or consulting the user manual. You can also check the region code of the DVD you are trying to play by looking at the back of the DVD case or consulting the information that came with the DVD.
If the region code of your DVD player does not match the region code of the DVD you are trying to play, you will see an error message like the one you described. One solution is to try setting your DVD player to a different region and trying to play the DVD again. However, keep in mind that most DVD players can only be set to a particular region a limited number of times, and once the limit has been reached, the region code can no longer be changed.
It's also worth noting that some DVDs are encoded for multiple regions and will play on any DVD player, regardless of the region code. If you have a DVD that is encoded for multiple regions and it is not playing on your DVD player, there may be another issue at play.

Each DVD player is assigned a code for the region in which it's sold. For example USA/Canada are Region 1 players. DVD players will refuse to play discs not coded for its specific region. In effect, this means that a DVD purchased in one country is normally unreadable on a DVD player bought in another region.

If your rental DVDs work in the player then there is nothing wrong with your DVD player. If you have purchased DVDs that do not work the problem is with the DVDs you have, not with the DVD player.

DVDs are coded for different areas of the world. If you bought the DVD from an online source it may not play on your format of DVD player.

Hi, if its saying wrong region. then either your player or disk is incompatable. region 1 ntsc ( USA ) Region 2 ( UK ) et,c. check your players region coding is compatable for your country, and that you are also playing a dvd with the same region coding as the player. alternatively is to try and find a region free or multi-region solution.

Zenith unit has playback issues.

I fixed it for good by sending the unit to DVD player heaven!

when i press play on my dvd/cd player it says error

Without the DVD in the player go into your setup menu. Arrow down to the icon that is a lock press enter. arrow down to password and if it says new or change select it. you need to enter a pass code so that when the prompt comes up you can override the parental limits.
if you need to clear your old security code because you have forgotten it the manual says to input the 6 digit number from teh setup menu "210499" I did not do this as I had never set up a security code but the Across the universe DVD will play as long as enter the security code.

its a mechanical problem from the disc tray section.The disc tray dosnt lap well inside,call your tecnician he will know what to do.

I wonder if you are trying to play burned dvds, if so that could be a major issue alot of players won't play burned disks, others will only play certain ones. another thing I have had problems with, though i don't know a fix. My samsung sometimes has a similar issue where it flat out will not play certain company dvds.
