Blank DVDs not recognized

[Spideynw]

I have an external usb dvd recorder and Windows XP SP3. I am not sure how to figure out which one, since the maker is not listed on it.

Anyways, it will not recognize blank DVDs. It recognizes movies and music cds. It wasn't recognizing blank CDs either, but I went into My Computer, and then to the properties of the CD-ROM, selected the recording tab, and checked enable cd recording, and now it recognizes blank CDs, but it still does not recognize blank DVDs.

I am trying to use DL DVDs, and on the outside of the DVD drive it says DVD+R DL.

Any ideas?

First thing I would try is get Imgburn if you don't already have it. Set the option in Tools Setting Write Tab, "lock drive for exclusive access" and try to burn a disc. An erasable is ok for the test so you don't waste a blank. If some other software has control of the drive you should get an error.

Let us know the result.
