SMC 330 dvd player problem
 

Hi! I recently bought a SMC dvd player model 330 because of its price and multi-region capability. But I have a problem with some dvd's where picture freezes in some chapters specially in the middle ones. For example, I have the dvd movie Anne Frank (new version) which picture freezes in chapters 15, 16 and 17 also I have a region 2 dvd that when I switch from PAL to NTSC picture freezes immediately. I notice on the specifications of these dvds that it says "dual layered format" or DVD-9. Does anyone have this problem with dvd formats? If anyone has this dvd player I would like to know if this occurs to you too. Thanks..
