Change the Video
Format to PAL or NTSC.

Problem
After stopping the player,
I push Play but
sometimes the DVD
starts where I left off
and sometimes at the
beginning.
The auxiliary source is
running but there is no
picture or sound.
My disc is stuck in the
player. The Load/Eject
button does not work.
Recommended Action
If the stop button was
pressed one time, the
DVD player resumes
playing where the DVD
was stopped. If the stop
button was pressed
two times the DVD player
begins to play from the
beginning of the DVD.
Check that the DVD
player is in the auxiliary
source mode.
Check the auxiliary input
connections at both
devices.
Turn the DVD power off,
then on, then press the
load/eject button on the
DVD player.
Do not attempt to forcibly
remove the disc from the
DVD player. This could
permanently damage the
disc and DVD player.
