No, we don't have a water softener, and we probably need one. We have very hard water here, and it etches things after a time with mineral deposits. That's what the white film seems like, but it also seems to be partially a detergent film, too. I'm using the same Cascade detergent that I always have, but this problem has just begun in the last three months or so.

I do use that Jet-Dry rinse aid stuff and always have, but that doesn't seem to be helping any more.
