Recently my van's portable DVD player will not read the discs. It just keeps saying No Disc on the screen. I have tried cleaning the laser with a small amount of alcohol on a q-tip and also resetting the factory settings, but neither one helped at all. Does anyone have any suggestions? We are set to go to Florida on Wednesday and it will be a long trip with four kids and no movies. Thanks. BTW it is a Venturer PVS 1950-D.
