Installed music doesn't show up in Pinnalce Studio
Pinnacle Studio versions prior to v.9 Plus (9.3) sort the music by style only. So when you add a new CD the music from that CD is forced into the style categories which already exist. So, for example, one track from the Memories CD will fall under "Orchestral" and another will fall under "New Age/Easy". If you would like to verify that the music is available, you can select "All" from the Sytle column and the Song column will be sorted alphabetically. As stated before, Pinnacle addressed this issue in their latest release.
