Seen this a few times and just wondered exactly what it means? I always thought it was a network related issue (eg. Strato playing from a Terra), but recently was doing some work in our system and accidentally pulled the network cable from a switch that connects a Strato with our network, the Strato kept playing the movie which led me to believe it was caching the movie to some extent. Guess there is a chance the movie was located on the Strato, but not likely as it was a very recent 4K movie and there is a lot of room on my Terra. Just curious. Thanks. SJ
