Update Roll-Up Logic for DVDs and Blu-Rays
Right now, the roll-up logic for DVDs and Blu-Rays uses the publisher information in addition to title to identify between different editions. However, there are a number of older films that have been republished by a new distributor, even though they are the same film, and despite being basically the same, do not roll-up. "Dune" (1984) is one example. "Fire Walk With Me" is another.
I think it'd be better to use "director" as a roll-up criteria as that's (almost always) unique to items with the same name. If someone who knows which cataloging field that would be, it'd be very grateful for the input. TV...gets complicated, I admit.
Ideally, these would be classified at the "work" level rather than the "expression" level but I'm pretty sure our MARC records aren't set-up for RDA like that.

Another idea here might be to allow the 130 field to be considered in the roll-up logic for JUST movies (240/130 was removed from consideration in roll-up logic because of issues it caused with print titles) so that catalogers could enter the "uniform" movie title there and trigger the roll-up that way. (The 130 field does provide disambiguation for works with the same name by including the year.)
