Hi Linda,
I work with a lot of smaller theatres maintaining their web sites and updating showtimes. To do this, I work fairly extensively with Cinema Source, as that is where my data comes from. They are really quite easy to work with, and in my experience they have always been happy to work with theatres to ensure accuracy. If you call TJ Albright at Cinema Source -(203) 438-8389 - I am sure he will be willing to work out a system with you to check your schedules and correct them quickly if there is an error.
Of course, in my business, ensuring the accuracy of showtimes is vital. If you are interested in an intermediary, I'd be happy to talk to you about how my company can make this process even easier for you.
