Lots of things could be wrong. They could have not provided enough
duct capacity to the media room. Or it could have no returns. Or a
duct could have been improperly installed, wrapped with a little bit
of tape, come loose and is disconnected. My guess would be that the
media room is at the farthest end of the run.
Do an inspection of the ducts and returns in that area. Find out
which other rooms feed off the same duct route. Then close registers
on rooms that are cooler on the same path and make sure everything is
open in the media room. What volume of air is coming out of there
now? It should increase when you close off some of the other
registers on the same ducting.
Check the attic venting and insulation. Is the attic well vented
with soffit vents and hopefully a ridge vent? Is insulation in place
and also not blocking the soffit vents? Placing a radiant foil
barrier against the rafters can also help.
