I'll leave it to others to speak to how the online database should have this profile named.  Not familiar enough with the contribution rules as it relates to double features.  That being said, the profile in question already exists, so here's an idea.  If you prefer a different naming just change it, lock the title data down and move on.  What does it matter if the current title doesn't best represent the contribution guidelines?  What does it matter what the collective thinks?  It's your collection.  Make it your own.  Personally I'd name the profile, "Peanuts Double Feature: Snoopy Come Home and A Boy Named Charlie Brown", then adding disc level profiles for each feature.  Again, whether that complies with the contribution guidelines is beside the point.  I have no desire for my collection to be a mirror image of the Invelos online profiles available for all to download/update and as long as I don't contribute something that falls outside the contribution guidelines no harm, no foul.
