How to access XviD post-processing outside BS Player

[durerca]

With BS Player, when you have a XviD video playing you can right-click and access the XviD decoder properties to adjust the post-processing settings. I would like to know what file BS Player is using to access these XviD decoder settings. For instance, with DivX there is a config file in the DivX codec directory where you can access these settings. Basically, I was wondering where this file is for XviD so I could access it without having to go through BS Player.

The reason for this is that I would like to help my parents (who are overseas) watch a XviD movie using Windows Media Player but I would like to set XviD to use post-processing. It goes without saying that showing them how to install BS Player would not be easy.

Thank you for any help.
