New installation teething problems

It sounds like these problems are caused by Genre not being tagged correctly in some of your files. Your test with the Genre index confirms this. You should not be seeing Genre index entries like (17), (80), and (186). If your tagging were correct, these index entries would be shown as Rock, Folk and Podcast.

This is likely to be caused by a mismatch between what EasyTag is writing to your files and what MinimServer is expecting based on the ID3v2 specifications.

Are the files that have this issue tagged using the ID3v2.3 format or the ID3v2.4 format? Your tagging program should tell you which of these formats the files are using.
