DVD crashes DVD player

This happened last night.  Was playing a Netflix DVD in my plain Jane  Magnevox DVD player.  After some 20-25 minutes of playing the disc, the picture froze and the sound stopped.  And, the player refused to respond to the remote control or the front panel buttons.  The bad code read in from the disc crashed the microprocessor in the player so hard I had to unplug the player and plug it in again to regain control. 
   We know that the DVD structure includes player commands to move the read head, jump to another spot on the disc, freeze the video, disable fast forward and other things.  That's how those menus at the start of the DVD work.  Presumably some damage to the DVD mangled a player command.  And the player code has a bug in it too.  Properly coded players should examine all player commands read from disc and reject any unknown commands or improperly formatted commands.  Halt and catch fire is never a valid player command.  Looks like my player ain't properly coded.
