Apologies is this doesn't come out right. Am on mobile and can't access PC for a few hours.

In regards to your statement re: bandwidth limits, that's exactly how I thought it works. Which was why I was confused that setting it below the bitrate resulted in no playback at all. But I'll tackle that problem separately.

Edit: once I have access to my machine for better navigation, I'll compare this media info with other episodes in the series (which all work and are from the same group).
