Why doesn't Zoom Player remember it's DVD Decoder Settings?

When trying to play DVDs, Zoom Player will initially prompt you for your DVD Audio/Video decoder settings. If these settings are not being remembered when loading Zoom Player again, then your version of Zoom Player might have been tampered with and you should make sure to download the latest version of Zoom Player from a validated source.
