HP DVD1040 STOPPED RECOGNIZING DISCS - HP DVD1040i 20x Super Multiformat Dvd Writer, Internal Burner

I bought this HP1040i for $20.00 after rebate from Fry's my computer OS Windows xp professional service pack 3, It can read only bootleg copies but not Original dvd movies. It came with Nero 9 Essentials. Do you have any solutions to this problem?

This is normally due to a lens issue. If you have tried a cleaning disc (one with iso-propyl alcohol solution) and it still does not work, you can also remove the cover, and use a qtip (ear bud) with some iso-propyl alcohol to clean the lens.
Mine for example the lens was clean, but a cat hair was stuck in such a way that it interfered with the laser, but would not come lose. a simple tweeze, hair gone problem gone.
Unfortunately if the two cleaning steps yield no results, it is better to replace the drive, as repairing it cost more in time and labor than to replace.
Hope this helps.
