Glad to hear that I am not the only one having this problem.
If you need a workaround you could use ffmpeg to convert the EAC3 streams to AC3.
You need to scan the file for the given streams with:
ffprobe -i [filename]
Write down all numbers for the EAC3 audio streams.
The folowing command will copy the video stream, all other streams (audio and subtitle) and will convert the defined audio streams to AC3 audio streams. The folowing example would convert just audio stream 1 and 3 to ac3.
ffmpeg -i [input-filename] -map 0 -c copy -c:1 ac3 -c:3 ac3 [output-filename]
Just remember the last matching command on a stream will define how a stream is handled by ffmpeg.
Tbh. I already started doing this as I reached out to @ChuckPa the last time. But I think I have to simply convert my movies…
Hope this helps you.
