Play DivX (.OGM) files without registered filters?

Hello all, I would appreciate a little help.

I am trying to play DivX movies with OGG audio (.OGM) on a PC where I have no access to install filters.

In the past I have used BSPlayer which would dynamically load filters if they were in the same directory.
First of all, does this method still work?
If so, which files do I need in order to play DivX5 video with OGG or AC3 audio?

If this is not the way to do it, is there another method I could try?

Many thanks in anticipation,

Cheers, Beastie.
