Why my DVD player doesn’t play movies?

[megancheung]

It doesn't play any DVD’s prerecorded and recorded by me personally. I have changed the settings several times but still the same. It just says "loading disc..." then says no disc
It plays audio CDs fine, but it should play DVDs it is a DVD player.
Here is my car DVD player what I brought two weeks ago:
Kia Sportage car DVD player
Does anyone know if there is any way to watch iPod movies on the DVD player in the car?

I'm assuming the pre-recorded dvd's (bought one's) play ok on a dvd player connected to a tv, if so check if there is a switch on the dvd unit where you can select "PAL", "PAL" is the video system or standard we use here in Aust, also check the units menu/setup to see if "PAL" is selected.
