I want to purchase the ASUS blu ray reader below: https://www.newegg.com/Product/Product.aspx?Item=N82E16827135247 and from reading the reviews, I became aware that I would need software to make it actually play Blu ray movies. Someone wrote about Cyberlink's PowerDVD as a solution, but I am unsure if this will solve all software issues. I am also unsure if I need to purchase a cable to attach it. I already have a DVD player which I want to replace with the new blu ray, so I am hoping that I can use the cable already there? Thank you for your help.
