OK, I've read where this has happened to other users, and I've had happen twice now. The MPEG option disappears from the "Save As Type" list in the Render dialog. The first no amount of re-installing VF or the MPEG plugin helped. I resorted to re-installing Windows.

The only thing I can point to as a possible cause is that I have just installed MGI PhotoSuite 4 Platinum.

Does anyone know how to correct this problem (short of a re-installing Windows)?
