model SD-V593. Factory pressed movies seem to play fine. I've had problems with some burned DVDs. Sony discs always worked, some Fuji discs worked but not many, some Memorex worked. Tonight even a Sony disc started causing me problems. ALL work on my cheaper Samsung player as well as my computer. This Toshiba is a higher quality machine with upconvert capabilities. I would think that it would play anything my lower quality machines do. Do I have a bad one. Should I bring it back and try a new one? Is it possibly something in setup?
