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

[Bruiser]

Running WinXP (Home). BSPlayer (build 492) would normally default to using WinDVD's codecs for MPEG-2 playback, which worked fine. After installing nVidia's NVDVD player, it now defaults to those codecs, which screws up the video. Uninstalling NVDVD puts the defaults back to WinDVD.

How can I point BSPlayer to WinDVD's codecs, so that I can have both it and NVDVD, and still use BSPlayer as my default MPEG-2 player? I have created a "Filter" folder and put WinDVD's codecs in there, but I guess there's more to it, as that doesn't work.

Any help appreciated.

<EDIT>
OK, I figured it out, at least how to write the bspfilter.dat file, after I searched the Registry and got the CLSID's for InterVideo's codecs.

BSPlayer now uses those codecs; the problem is now if I click on the position bar, I get a "handler exception: EIP00493482...invalid floating point operation", yada, yada...

I've seen other posts about this, so I'll look, but, in the meantime, if anyone has an answer, thanks.
