It was a series of very old bug.
1) After the passage to the WX system the CoInitialize was not anymore called on the GS thread causing the Filter enumeration on DirectShow to fail.
2) After the "MFC Free" commit of Gabest, if you selected the Uncompressed functionality a nullpointer exception trigger (as there is no filter for that)
3) Strangely there was no code path to connect the source with the mux when Uncompressed was selected (without an encoder in the middle). I added it.
Test it and report problem. I already know there is a problem with the closing of the sound recording, but that's a PCSX2 problem, not a GSDX one.
