FTR, 1/20th of a second (50ms) is a longer exposure than 1/80th of a second (12.5ms), and thus more vulnerable to camera shake; I'm guessing you meant 1/320th of a second (just over 3ms), especially since both boosting the ISO four fold and increasing the exposure time four fold would tend to overexpose the photo.
Indoor shots with strong backlighting are tricky unless you're going for a silhouette effect; fill flash often helps balance the lighting.
