I just upgrade to the newest version of nero7.5.9.0. Does any one know exactly what the "Microsoft..Directx 9..." was all about that needed to be installed.Does this have anyhting to do woth being VistaReady Compatible I read the eula but wasnt exactly sure what this was.Went ahead and installed it though. Will this interfere with me making dvds out of my recorded Tv show or DVds. Because Im trying to make a dvd of a recorded tv show and I dont have audio on a few of my shows when trying to edit it. It'll play fine in the in all my players though. If so how can i find out where this "Microsoft Directx..." is on my computer and replace it with my previous version. Will I need to roll back to the previous version of nero as well?? Where can I find it Ionly have 7.2.7.0 Any one else have this problem yet?
