In MP2 Spr. '16, I have 2 columns and 2 rows set in TV Configuration, Recording, Thumbs. However, I only get one large preview picture (as if I had 1 column and 1 row), rather than 4 smaller preview pictures offset in time. This feature worked fine in MP 1.12.
Bottom line feature request: Make 2 column by 2 row Thumbs (not just 1 by 1) work in MP2 .
