Hi Shane, I share your concern about preservation-ready repositories, but in this case I think we can have our cake and eat it too... and I think this is just a different way of saying what you said.
There's no reason that the repository couldn't store an archival master copy of the video that is restricted to, e.g., the repository administrator, and also have a link in the metadata to a delivery copy, wherever it resides. It would be nice if the delivery copy could be delivered right from DSpace, but for special or odd formats that may never be practical (think of proprietary formats like AutoCAD or ESRI). Lots of digital archives make the distinction between preservation and use copies, and consider the use copies entirely disposable and reference them for the users convenience. Does that make sense to do here?
