Help with DVD Drive

Hi

I spoke to ASUS support and they are telling me to do a factory reset of my computer. I tried the movies in another ASUS laptop and they worked fine. The CD-ROM drive works fine but it does not recognize the DVD movies. It recognizes any other disc I put in.
Do you have any suggestions?
 


I have the exact same problem on my ASUS K55DR. Did you find a solution?? I would be very interested in that...
