I have 2 Stratos and 2 Altos (as well as a DV700). I have a lot of bluray quality movies stored on my Stratos as I had those prior to the Altos. How can I move HD (not 4K) movies from my Stratos to my Altos to create more room on the Stratos for 4K movies including HDR versions? I guess I could delete them, unplug the Stratos and redownload, but what a pain that would be. I know that Premier line has this capability, but can't seem to find anything. Also sent the request to my dealer. Not a high priority as I still have plenty of room for 4K at this point. Might also be nice is this was automatic. If there was not enough room for a 4K movie, the system would move movies automatically to make the necessary room. Thanks. SJ
