I am using Windows 7 Ultimate.
For some reason, the majority of my songs and movies (80%, nearing 5000) have a "stop time" checked – which I did not put on (under Get Info » Options). This is extremly annoying as some movies will only play for 10 seconds and some for 2 hours.
I don't want to go through every file individually as this would take days. How is it possible to mass-unselect the stop time and/or start time?
Note that it's not a issue of corrupted files since when I deselect the stop time, the song or video fully plays to the proper ending.
