I am sorry for the delay in my response. Yes, it is transcoded video she is watching. She is at her house, use a Roku, my server is transcoding for her.
I'm really suspicious this was/is a network issue for her. She has the lowest tier plan from her ISP. Plus she is on wireless with the Roku. Maybe one of her kids was doing something on the web at the same time. I don't know. But I have a feeling she is probably really low bandwidth. I'm trying to keep the communication flow going but surprisingly the people that have the problems often don't want to work with me to fix it. So I will just let it go until she calls my wife again and complains. At that point, I'm going to have her back down her bitrate.
I also tried to get a speedtest off her droid standing near the Roku so I could get some idea of what her down is like. She didn't do it.
I'm leaning towards this because 1) she watched it before with no problem 2) other people connecting to my mb3 with rokus are not complaining.
So we will see.
And I think I mentioned this before but hopefully my server is not to blame. It is i7-4770, 16GB ram, OS and apps are on SATA3 SSD, my ISP connection is top tier (105Mbps/22Mbps). Everything LAN is gigabit. Slowest component is the Drobo 5N (as far as R/W speeds), where everything is stored, yet it still should be plenty fast enough for all of this.
I'll post back if I collect any more definitive info to go on, or I am able to conduct some tests myself.
