Hi, I'm currently using MediaMonkey, but was thinking about migrating to MusicBee, as it's far more superior in many aspects, less buggy and has the best synched-lyrics plugin I have ever seen. The only things that prevent me from doing so are basically related to lack of video support in MusicBee.
My whole video-library consists of tagged mp4 files with two audio-tracks and (.ttxt) subtitles inside those mp4 files. Current version of MusicBee is able to read tags from mp4 files, but doesn't write changed tags in those files.
As for video support the only built in features I need, aside from video itself, are the ability to change audio-/subtitle-tracks and the ability to show/hide subtitles. I don't need built-in codecs, as I prefer to use K-Lite codec-pack.
I hope someday MusicBee would have this features.
