Some visualizations like this one:
http://visuals.free.vovoid.com/view...29uaXF1ZSBwbHVnaW5z&name=c3RhcmxpZ2h0YXVyb3Jh
when initialized change the current working directory to the one in which they are installed. This may cause problems for other parts of MP. The example I have seen is that the vmr9.log is not created (the code tries to create it using the relative path "log\vmr9.log" and there is no log directory in the visualizations directory). Not sure what other things this may impact.

To reproduce:
1. Set the MP logging level to Debug
2. Start MP.
3. Turn on TV
4. In your log dir you should have a vmr9.log file.
5. Exit MP
6. Install the above visualization
7. Select it in the MusicPlayer settings (using Bass player).
8. Start MP
9. Turn on TV
10 In your log dir you will not have a vmr9.log file

Let me know if you need more detail

That was the reason to introduce the config provider half a year ago

If you spot areas where MP is still relying on relative pathes for criticial methods please report those.

Well it's certainly not critical but the "log(...)" function in
Core/DirectShowHelper/DirectShowHelper/dshowhelper.cpp
certainly assumes that the media portal directory is current... I'd submit a patch but I don't have the capability to compile that code. Perhaps MrHipp could take a look, if he is passing that way again!

Thanks
