Found lost videos from 1969!!!
The store I called yesterday,and I'm taking the film's to today, said the same thing. If we watched them several times on this ancient projector without any problems, they are still in good enough condition that they wouldn't have any problems with them. They told me of the risks with old films, but they're pretty confident there won't be any issues since we were able to play them several times. Dropping them off as soon as I leave work!
