Massive LCD screens aren’t always kind to DVDs, leaving much to be desired in the picture quality. Here’s where your PS3 comes in; it has a processing grunt to polish them up to near HD quality.
“While watching a DVD through an HD display, press the Triangle button and choose the AV Settings button, you will then see options for frame, block and mosquito noise reduction, and also an option to perform a full upscale on DVD content.
Video saved to storage can also be run with frame and block noise reduction by tweaking the same menu options.”
