Looking at MovieRush I'd say that you just need to load up JR5, enable the video modules, pick a stock skin and off you go.
EarthRush maybe has a couple of features that JR5 doesn't have atm (chat, ads) but it would still be a good starting point. The Aparna module could create an ads module for you, then build your own chat module (it would likely be a good seller as well).
