I am using JRiver MC for ages now. The program does a lot of good things but for a long time I am waiting for improvements (fixes) for the sync proces with devices.
I am having problems with the sync of playlists to my Android Phones or actually the Micro SD in it. I sync around 50 playlists, around 12.000 Flac/Mp3 track on my 400Gb Sd card in the phone.
It is only JRiver MC that has a problem with it. Both MediaMonkey and Musicbee don't give me any trouble. They even sync through Wifi.
While syncing it suddenly stops. No clues what goes wrong. The songs are on the sd card but MC wants to sync again. Sometimes the JRinfo.xml is suddenly missing.
So I thought, OK take out the micro SD Card and sync it. That works well but I don't like taking it out every time that I include a new song in a playlist. I also notice when using the SD Card it does not makes a JRinfo.xml so MC wants to sync all over again but ofc ourse the card is already full.
