I get a TV Access rating from your scanners, and that shows in theater view. I don't get a MPAA rating from the scanner, and when I add the value it doesn't show in theater view. My guide data has us tv ratings but it doesn't look like its being mapped to the Access rating field that shows in theater view. I can take a second look but it appears that my choices are preserve the original metadata from my guide data and get not rating, or let your scanners pickup the the show data, and get a rating. I would like to preserve the original if that's possible. Your scanners don't always pickup the correct show data, or at times they just can't find it, which makes it easier on my end to preserve the original. When I try to use metadata from a mix of the scanner, and the original guide data MC displays the show as two different series, and it creates confusion for someone who is just trying to watch their show. When you get some time to look at this are you able to reproduce the problem, or suggest any fixes?
