I was under the impression that 720p took up more bandwidth than 1080i because since it's progressivive it has twice as many fields. If 720p is equal to 1480i then why would a projector have more trouble resolving 1080i and be able to do 720p. Can you correct me if I'm wrong please.

These E-Cinema setups have their source material mastered from 1080p digital sources, with 4:1 proprietary compression used to get the image down to the native 1280 X 1024 display resolution.
The bandwidth for these presentations obviously needs to be 10-20 times what broadcast 1080i or 720p needs, and that's why the movies are hand transported on hard drive packs to each theater.
