Actually, that screenshot is of FMC (Free Movie Classics), and this Free Movie Classics, not Family Movie Classics, is the channel showing Porgy and Bess, although incorrectly as you stated. (showing "The Last Alarm.")
They also have an Android app called FMC (Free Movie Classics), but is also showing the wrong movie. The Channel developer has an email contact at firstname.lastname@example.org.
Looks like the developer is currently doing some updating/developing as FMCTestWestern with No Ads is present in the Roku Channel Store, but FMC (free) is not showing, although I currently have it installed on my Rokus.
