iXpand and Netflix

So, I’m looking for options to store rented downloaded movies to an ixpand base for simultaneous streaming to three iOS devices (for road trips). It sounds like both iTunes and Netflix are not options due to formatting restrictions, do you know of any other options? I am specifically asking about downloaded rented movies as I do not want to burn data (by streaming video) on a 10 hour trip and I do not want to purchase movies. Any offerings?

I think you have precisely the hardware option I’m looking for, but are challenged by the software restrictions of downloaded movies.  If you are able to solve this last issue, you would have a winning combination of hardware and software that many families are looking for!
