Pan-scan's strange relationship?

[Farlight]

Seems like your Pan-Scan don't get remembered because "cut top and bottom" has nothing to do with Pan-Scan. If you get black bars on both left/right and top/bottom you might have "don't resize video in full screen" checked. I would uninstall delete all settings and reinstall the latest BSPlayer and see if it goes away if you have this problem for all the videos you play.
