I've been watching (listening) the Australian Open replays on WatchESPN, and it seems that every video that is longer than 4 hours 19 minutes stops around 4:19.
I've tried watching on different computers ( i7 950 with 16GB memory, i5 3570k with 16GB memory, and i3 3240 with 8GB memory, all running windows 7 pro or ultimate on SSD drives, also on laptops with lower specifications). The audio and video simply stops even when I'm at work on a Comcast Businessclass Deluxe 100. This happens when there is no other activity on the network (ie. I'm at work alone, working on various issues but listening to the audio).
It even stopped for the Australian Open final between Murray and Djokovic.
This happens randomly. And nearly everytime, when I ask to replay the video, it asks me to select comcast xfinity, and login to comcast again.
So I'm wondering if this is related to the WatchESPN 308 error / Comcast authentication.
