Try using vinegar, CLR or lime-a-way to clean them. If they get clean, there were minerals causing the problem. If it doesn't clean them, they are probably etched. You can prevent etching by using less detergent and by making sure you don't rinse the dishes too much before putting them in the dishwasher. If you don't have food on the dishes, the detergent will attack the finishes of your dishes.
Run your dishwasher with C.L.R follow the directions on the package ,Also make sure to run the hot water to your sink until it is hot before starting the dishwasher every time you use it as the detergent will not work if the water is not hot enough
try soaking the glasses is a 50/50 solution of white vinegar and water for a while and see if that doesn't remove the films. some glasses do that in the dishwasher and need to be hand washed.
