What kinds of problems have you encountered to say that the build is 
quite unstable ?
does it crash at any time or during negociation or state transitions ?
May be the crashes are related to some debugs as msvcrt.dll doesn't 
support NULL parameters in printf arguments ...
I'll commit some changes to fix that because actually we can't use debug 
level 5 on windows from cvs.

Actually, i have not tested a lot of differents pipelines with gstreamer 
on Windows, but the ones i have tested were working fine.
Here i'm talking about the binaries i'm building with vs6 but i'm using 
binaries built with mingw+gcc for dependencies.
I ran some pipelines for ogg theora/vorbis playback, and i've concluded 
the core is quite stable on Windows (i mean once the printf problems are 
solved)...
