XP Update broke MePo & now can't watch ANY video (1 Viewer)

[Viscouse]

At least I think it did. Oh, I could really use a hand here.

MediaPortal Version: 1.2.2.0
MediaPortal Skin: Default
Windows Version: XP SP3

I'm almost positive all codecs are still good because yesterday the installation was fine, and played all/any video. Today, after a WinXP update, it doesn't and trying to play video results in this error box:

I can play the same videos I used to, or any/all vids using VLC and the like. So I'm 100% sure it's NOT the files, and pretty sure it's not the codecs.

I've read a few posts talking about making sure all the Microsoft Visual C++ 2010 Redistributable Package (x86) are up to date. I vaguely remember the update being about that.

Here's what I've done:
1. Panicked, freaked out and then lay for quite awhile in the fetal position.
2. Verified vid files are not the issue.
3. Tried to uninstall the latest WinXP update, but can't be certain I got the right one.
4. Found this thread, this one.
5. Verified that dshowhelper.dll is located in MediaPortal installation directory
6. Uninstalled ALL C++ packages using Revo, and dnlded & installed again.
7. Uninstalled MP using Revo, and reinstalled that.
8. Because of #7, now I don't have any of my !@#*& plugins anymore, so all plugins are deactivated (except MP-TV Series).

Any help is appreciated.

Hello!
From the logs you haven't installed any video driver. Please install one! =)
Catalyst 11.3 should work fine! I see you have installed one.. do you use a secondary display?

Can you install latest DirectX: http://www.microsoft.com/download/en/details.aspx?id=8109

First things first: Success.

I tried the DirectX as suggested, no joy. But at least those are updated now.

I will admit you did give me a small heart attack when you suggested I didn't have a video driver installed. How was I able to see anything then? To answer your question, yes, I do have a secondary display (an LCD in the HTPC).

That did ring a bell for me though. Something else I noticed that was borked was the resolution of that LCD. It changed and I couldn't get it back the way it was supposed to be.

I looked at my video driver and it says it's current as of 2011. So, I gambled and rolled it back. Now, using something from 2008, EVERYTHING IS FIXED. So needless to say, I'm very confused as to why that caused an issue, but happy.

I have to go reinstall all my plugins now. Joy. Thanks for the help Holzi!
PS, I just finished BrBa...it was wicked awesome. The last episode was the best in the entire series.
