Initial IDM-9520 Portable DVD Player with 4-Inch LCD and Car Kit
Mine Quit working also
My Model IDM-9520 worked great for about two movies.  Now it is all I can do to get thru one movie.  It will freeze after about 10-15 min of run time. Only way to recover from this is to shut down and try and reload the movie(which does not always work).  Great price, but definatly not worth the aggravation.
