Hi i have had a laptop for a while and when i bought it came with a dvd burner. The Toshiba SD-R6112. At the time i couldnt afford blank dvds so i stayed with cd-r's that i had for a while from my last burner (on a desktop). I finally see a sale for some TDK DVD-R's. It says they are 4X. But when i put the blanks in i just keeps reading them or it wont detect them. I used Dvdinfopro to see if my burner is compatible and it says it is. So my question is it something to do with my OS and if so what can i do about it. Any help would be appreciated. Thanks in advance. oh btw my os is WinXP Pro. Thanks agian.
