What DVD+R media for a Toshiba SD R6252 burner



I have a Toshiba SD R6252 dvd burner in my hp laptop. Ihave no problems writing and reading any DVD+RW disks. My problem is that after writing to DVD+R disks the majorityof time the burner will not see the DVD+R disk. These disks can be read by other computers and some dvd players. Can you tell me which DVD+R disks I should buy. My dealer says the drive is ok as he was able to burn and read one of his disks.
