Neither of my OEM DVD burners will read a DVD. I get an error message that says a DVD Decoder may not be installed. Do I need to buy a third party DVD Decoder? I can't find them on the manufacturer's website. They read audio CDs, and the Pioneer will burn audio CD's, but I also cannot get the Samsung to burn a CD. (Pioneer DVR 111D & Samsung SH-S182M). What do I need to do guys? Thanks in advance.
