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 will resume playing where the DVD was stopped. If the stop button was pressed two times the DVD player will begin to play from the beginning of the DVD. Check that the DVD player is in the auxiliary source mode.
