I don't even know how to research this one.
Their broadcast engineer said
"When the content just changed, the transcode on our transcoder stalled. This happened several times. I have to go in and re-submit it. We will need to try and figure out what is causing it. "
which is a phrase that comes with *several* red flags, but...
I mean, even discounting the things he said that I would have preferred him to say differently, and the fact that the decoder can't automatically re-start when the stream fails (which is a huge problem!) I just have no idea how to research this one.
