How do I get BSPlayer to default to WinDVD codecs for MPEG-2

[Bruiser]

Xophile: you've got mail.

An update: I upgraded to build 493, and, while I no longer get the handler exception when I try to use the seekbar, it always shows 100%.

Has anyone found a way to get nVidia's filers to work? Those are the ones that BSPlayer will default to for MPEG-2. The audio is fine, but the video doesn't work.
