Looking at the vic\video\grabber-win32DS.cpp file from the Sumover VIC source code, there is a comment: //SV: XXX got rid of 422 format since there's no grabber returned for it and vic crashes As JPEG requires YUV422, the JPEG option gets greyed out when the DirectShow code is used, but not with the separate Video for Windows code.
