I started a thread some months ago about a problem with my HP640c DVD writer (really a BenQ 1625, as I understand) not being able to read DVD-R media. At all. Works with DVD+R media just fine.
That thread can be found here:
I tried all of the recommendations made there, including using better quality media (Verbatim) and flashing from the HP drivers to the BenQ 1625 drivers.
Flashing worked great, but the driver still does not read the media. For example: DVDInfoPro just keeps coming back with “No Media is present”.
AARRGGGHH!! This is driving me CRAZY!! Anybody else have any ideas on what to do to make this work? I would really appreciate any more help!
