Audiovox DVD1500 5.8-Inch Portable DVD Player
You get what you pay for
When portable CD players came out, we had problems with pausing.  The slightest twinge caused mine to pause.  I kept mine in the family room when I first tested it and it still paused.  I am returning mine because of this and the monitor did not work.  If I buy another one I am going to go higher quality and look for one that can take a few bumps.
