How can I eject a mini DVD?

try cleaning the lens with a q-tip and alcohol

Sometimes a dvd can be ejected manually but mostly the unit must be partially dismantled but if you try to do that you will invalidate the warranty - at only 5 months old it will be the responsibility of the supplier/retailer to cure the problem. I suggest you re-read the instructions and then contact the supplier without delay.
Then you should contact the dvd rental company and tell them what is happening.

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.6 Jan 2013

This has happened to me many times. The disk has an error (they alway do).

1: Turn it off.
2: Attatch power connection.
3: Hold down eject button.
4: It should say: "DISK ACCESS"
5: It may take a long time, but put it down in this state and leave it for as long as it may take.
6: Later on, it will eject the disk.
7: Discard of this disk, it's nothing but trouble.

Hi
I think the answer is in your question. Pioneer DVD-RW drive, DVD+R disc.
For some reason known only to Apple, some drives do not work with all discs. Mine will not burn -R dual Layer discs.

Hello sir/ma'am good day, all dvd players has this small circle on the center of the tray, where you play the mini dvd disk. eject your dvd tray to see. hope this helps. thanks

Won't play DVD's (store bought or burned) error message reads"UNABLE TO READ DISC" how do i fix?

i read in the manual that if a tape gets stuck to take off the battery and connect the AC line. surprisingly it worked.

If it is capable of reading DVD-R or DVD+R look at your manual it will tell you what formats it will take.

i had the same problem with mine i just kept hitting the reset untill it stopped.
