Why does my MPC still use DivX 5.04 for playback?

[sPunkt]

I have a strange problem with MPC still using DivX 5.04 for decoding. Of course, I currently have DivX 5.11 installed, and I had numerous other versions of DivX installed since 5.04 (including all the betas). In fact, I think I actually started using MPC, when I already had DivX 5.05 or greater. So what is the problem here? Could I have some directshow filters installed that I know nothing about??? I couldn't find any traces of Divx 5.04 except for the divxdec.ac that came with WinDVD 5. Since this resides in WinDVD's folder, I always assumed it wouldn't interfere with my system in any other way. What way is there to get rid of it (apart from uninstalling WinDVD)?

I think the windvd version of divx decoder is currently registered in your system and is using it. So first un-register this version..
go to windvd folder in command line and type:

regsvr32 u\divxdec.ax.

Then register the new one:
Go -> System(32) in command line
and type

regsvr32 divxdec.ax

(You need to check there exist a copy of divxdec.ax from divx5.1.1, if not manual installation of divx codec is only required...)

Thanks!

Haven't yet got around to trying it, but will do so soon.
