Congrats!
Merage would allow you to stay in So Cal and leverage some of your network there. Now, entertainment is very hard to get into, as you probably know. Merage is not going to help you with scoring a job in this industry (you will have to work the alums and even then it is going to be tough to land an internship or a job) - you will definitely have to work for it.
However, consider the outcomes and your classmates. Merage average salary is $100K and Tepper clocks at $140K. Sure it is more expensive but you will get it back within a few years. My main argument against Merage is that you will be attending a top 50 school in SoCal that already has Anderson and Marshall that are not doing all that amazing with their recruiting. You also throw in there Pepperdine and Loyola and you have a lot of MBA's chasing good jobs.
I don't think Tepper is going to be extra helpful in landing you a Media/Entertainment job but it sure will provide some back up alternatives and the caliber of classmates will be much greater - that's a big plus. You will spend a ton of time with them; they will be your network, and you are not just attending a school that has a certain ranking - the ranking mostly applies towards the applicants/students. I would suggest considering Tepper's offer seriously. Some people pay 4-10x more for a business class seat on an 8-hour flight. You have 2 years to go; not that much of a premium for going to a top 20 school.
