Before you ask, yes, I've installed Medibuntu. This codec is not in that pack--specifically I am trying to install SCLS.dll, which stands for Screen Capture Lossless Codec, a codec that works with CamStudio's desktop recording software.
It works fine in Windows, but when I have attempted to install it on Linux, I have had zero luck through Ubuntu itself, or through Wine. When I install through Wine, GOM player simply crashes and Windows Media Player won't load the files at all--those are the only two media players I know of that have correctly made use of the SCLS codec in Windows--and in Ubuntu, the "Videos" program can't find it--so I suppose the second part of my question would be how to direct the "Videos" program to my codec?
