I have a premiere xl4 in my living room and a regular premiere xl in my bedroom. I often use the multi room streaming to stream recordings on the xl4 to the regular xl. About two weeks ago I was streaming a program. Playback was fine then about 30 minutes into the recording the playback started to stutter severely. Eventually playback failed, I received an error about a loss of connection to the xl4 and the xl4 disappeared from my my shows list. I had to restart the xl4 for it to reappear in my my shows list on the regular xl. But since then multi rooming streaming to the regular xl never works. I can browse the list, start playing. But it immediately starts to stutter then fails. Over the past two weeks I have tried multiple times to restart every piece of the system. I restart the router, the xl4 and the regular xl. I even did a full factory reset on the router. Now if I stream a recording hosted on the regular xl to the xl4 that plays absolutely fine. I don't think its an issue of the quality of connection and the available bandwidth of my internal network. Everything is connected via wired ethernet direct to the same router. And high bandwidth hd video streaming from other services such as netflix, hulu and amazon work flawlessly on both boxes without any delay. Also in the living room I have another media streaming box that works absolutely fine. I have tested downloading a show to my xl from the xl4 and then works but the transfer rate is painfully slow.
