When I go to burn a back-up DVD to a -R disk my burner dosen't recognize the disk. I's as if there is no disk in. I have no problem with +-R,+RW,+R DL. The burner is a Phillips in a Dell P-4,3.0 gig.
thomas280, Welcome to the forum. You need to post the burner's model#. Philips has a lot of burner's. Are you sure it is supposed to do ( - ) DVD's
My burner is a Phillips #8601. If it ca burn all the other media types, why should there be a problem with _R disks? I am burning them only for use on older DVD players that have playback problems with the othe media types. Disk brand s don't seem to be a factor.
thomas280, The site below shows your burner is not capable of burning (-)DVD's http://support.dell.com/support/edocs/storage/P75084/en/specs.htm#supported
