Aspect ratio reseted each time the video is paused

[El Pollo Diablo]

The title says all, I use custom aspect ration for some videos, and since I reinstalled Windows on my computer each time i pause a movie the aspect ratio is automatically reseted to the default value.

This is really annoying, I went through the options and found nothing to correct that, I use Windows XP Pro SP2 and BSPlayer 1.32.
