Why does ''DivX'' movies need xvidcore.dll?

[kimiraikkonen]

Hi guys,
I have a movie encoded with DivX exactly. Plus GSpot prooves that.

And i ONLY have Divx 6.5.1 codec to decode divx and other ''generic Mpeg4 files''. Xvid decoder is not present currently.

But i was getting ''xvidcore.dll'' not found error message when i tried to open DivX files although they're encoded with DivX, not Xvid and I'm sure.

I solved that problem by putting xvidcore.dll to system directory of Windows.

But the question is: Why does Bsplayer and Divx need ''xvidcore.dll'' when opening a Divx file?

I didn't see this issue in Windows Media Player.

Thanks.
