I'm not sure why standard definition would be any different if that's what you meant.
They are copies of standard definition movies. The specs on the player says it supports DVD-R, but I'm not sure if that includes DVD+R discs. Besides playing HDDVD's, we also plan to use it as an upconverting DVD player for our std def movies, which were burnt onto DVD+R discs.
