Hi ajkessel, can you please let us know which file from the logs is one that was previously streaming and now transcoding? It is possible that one of the bugs we fixed has caused this because of an incorrect renderer config, but we can't know without that extra info

In order to know what the situation is I just need to know a filename to look for in the logs. We have added heaps of custom logging throughout the application that is usually enough to tell us why the program is making these decisions.

Well that log snippet shows part of the picture. It shows that we have detected the subtitles correctly and determined they will need to be transcoded. We also need your configuration file and the renderer configuration file, and it would be useful to reproduce the error fully by playing one of the files before making the logs.
All of these things are in the Problem Reporting Guidelines above.
Feel free to PM the logs to me if you don't want them attached here.

The snippet above shows that the file being parsed has EIA-608 subtitles:
This is a type of subtitles often used for hearing impaired in the US as far as I know: https://en.wikipedia.org/wiki/EIA-608

UMS was doing the incorrect thing before, and we fixed the bug where it was streaming when had things to transcode.
We can see in the logs that the language of the subtitles isn't detected, so it should match "und", and by default UMS will attempt to transcode undefined language subtitles.
There are program settings you can change to prevent that. If you go onto the Transcoding Settings tab, and the Subtitles settings subtab, you can change the "Audio/subtitles language priority" setting to reflect what you want, or you can simply check "Disable subtitles" if you never want them.
