I bought a new 716a installed it in my system today. The computer recognizes the drive but it does not recognize any media that I put in (such as, dvd, dvd+r, dvd-rom). I checked the windows task manager and found that plextool.exe is running at 50% cpu but I am not doing anything with it. I removed the Intel IAA after reading about it in the faq, but the problem still exits. DVDinfopro and nero says no media present after I insert dvd+r. Has any one experienced this?
