Is this a stand alone dvd recorder or is this a dvd drive in the computer?
If it is a dvd drive in the computer you can run Nero InfoTool, which will show what type of disks this drive can burn: http://www.nero.com/enu/support-nero8-tools-utilities.html Free to use.
You can just tell us the model number and we should be able to tell you that way too. (for a drive or stand alone recorder)
Hi and Welcome![QUOTE=The_Trillionaire;2222590][qanda]This thread is about the Samsung DVD Recorder. Click here to see full specs[/qanda]How can I tell if my samsung dvd burner is a DVD-DL?[/QUOTE]Just read the manual, that came with the unit.
If you read the specs it does tell you the media format it can write and as the MOD says one has to read the manual first.
"Optical disk recording - DVD-R, DVD-RW " there that was from the specs sheet.
