I am burning already copied DVDs using InterVideo DVD Copy2 to MAXELL DVR-R disks. The new DVDs play fine on the PC burner but do not play in my Sony DVD player. The manual on the Sony player says that it plays DVD-Rs. In addition, the DVDs that I am copying from are also DVD-R and those play fine on the Sony DVD player. Am I copying these DVDs wrong. Somebody please help!!!
