Divx Web Player sometimes without audio (AC3 issues?)

[frosse]

So I use Divx web player quite a lot to watch videos and usually I have issues with either video or audio but sometimes no audio at all.

I think it's when I play videos with AC3 Support that I get no audio.

I have Perian installed, but their support page says the following:

Please consider removing obsolete QuickTime Components: FFusion, Xvid Delegate, 3ivX, DivX, DivX Decoder, XviD, msmpeg4v1, msmpeg4v2, AviImporter, EX_M4S2, Casio AVI Importer, AC3 Codec, and MatroskaQT.

Now, in my QT folder (library/quicktime/) I used to have an AC3 filter file, which I deleted, nothing happened. The only file in there is Perian.component.

Is there somewhere else I should look or is that not the issue?

Please help
