My HP DVD writer has quit "seeing" DVD disks. The drive works normally with CD-R/RW disks but when I put in any DVD disk, (commercial movie, home burned or blank disk) it's as if the drive is empty. HP's on line "Instant Support" has been running me in circles for two days reinstalling the driver, changing the Registry, etc, etc, they even told me Imation and Memorex DVD disks won't work in a HP writer. (I had already burned I & M and HP DVD disks when the writer was working) Then when HP's "Instant Support" runs out of ideas they don't answer you again. I told them I tried swapping the DVD writers between computers and the HP does the same thing in my Compaq. The NEC writer (from my Compaq) worked normally in the HP computer. The fact that the burner doesn't work in 2 computers doesn't seem important;Q Anyone had a DVD writer with this problem?
