What is the model number of your DVD player? You may try power resetting the unit and check if it helps. To power reset, turn OFF the DVD player and unplug the power cord from the electrical outlet for 30 seconds. Plug the power cord back into the electrical outlet and turn the player ON. Attempt to open the disc tray.

Depending on the model number of your DVD player, simultaneously press the POWER + STOP + EJECT buttons. If the disc tray still does not open, simultaneously press the DISC1 + STOP + EJECT buttons.
NOTE: This step may not apply to all models as DISC1 is not available on all DVD players.

If this does not work and if the DVD player has DISPLAY and PREV buttons, press and hold the DISPLAY+PREV buttons for two seconds to unlock the drawer.

FOR SONY PLAYER's

This issue may occur if the disc is damaged or if the disc was not inserted properly into the Blu-ray Disc® player. Follow the steps below to open the disc tray and eject the disc.

1. Turn off the Blu-ray Disc player.
2. Disconnect the power cord (mains lead) or AC adapter.
3. Allow the disc player to remain without power for 30 seconds.
4. While pressing the OPEN/CLOSE button located on the front of the disc player, reconnect the power cord.
   IMPORTANT: For some Blu-ray Disc Home Theater models it is necessary to press and hold the OPEN/CLOSE andPLAY buttons simultaneously, then reconnect the power cord.
   NOTE: This step may require the assistance of a second person.
   
5. After reconnecting the power cord, when the tray opens, release the OPEN/CLOSE button.
6. Remove the disc.
7. If necessary, disconnect and then reconnect the power cord to recover the player.

turn on first the dvd player and wait to read a disc inside if no disc inside the tray it will say disc error. if the unit doesn't turn off, eject now the the cd tray. if get turn off, remove the cover then check for an stuck up gear or obstruction in the cd tray assembly. you can check also the power supply board which may have unusual parts like bulged or burnt component parts.

You should try unplugging the DVD player from its power source then plugging it back in. Now try to open it and if that doesn't work than you'll probraly have to take it apart to get the disk out but sometimes the DVD players can get worn out or if you have a cheaper DVD player it might just be freezing up on you. I have had these problems before. I just took the DVD player apart to get my disk and then trashed it.

Resolution Tip: Make sure the CD or DVD disc is not in use. Quit all applications that are using files on the disc.

1. Press the Media Eject key at the top-right corner of the keyboard.
2. If that doesn't work, drag the disc's icon to the Trash.
3. If that doesn't work, restart the computer, then hold down the mouse button or trackpad button while the computer is starting up, until the disc is ejected.
   To restart, choose Restart from the Apple menu.

One of the buttons has got stuck, so when you press the button you want to, its not getting the message to start / stop playing. This is also why the eject won't work. Either a new button, or replacement board would make it happen for you :)

There's a few things you can try. Turn off unit, unplug from AC for 5 minutes or so, plug back in, turn unit on, hit eject/open.
OR..same as above, but hold the eject/open button, then turn unit on.

Sometimes a combination of these odd procedures actually work. Sometimes holding the stop button, and hitting eject/open works too. Hope this is helpful.

FYI - This might damage the unit, but if you really need to get that DVD out then you can try this at your own risk!

Try unpluging the unit, then plug it back in and press the power button and a split second later press the eject button. This all needs to be done quickly otherwise the unit will try to load the disc.

Or

You can try letting the unit load the DVD. When the unit says "Please eject disc. Playback feature may not be avalible on this disc," press the eject button.

By pressing the Power button for >10 seconds you can force the unit to turn off. Immediately as the unit does, press the disk eject button and the defective DVD can be removed. Don't put it back in, or the problem may repeat!

Yes, I'm having the exact same problem -- I can't eject the dvd that's in the player right now either manually or remotely. It plays fine.
