This is caused by a problem with MinimServer update 260. This problem is fixed in the latest MinimServer update 263.

On the 3.93 firmware, the only way to remove update 260 is to select Initialize Settings from the Melco front panel Settings menu. After the Melco has restarted, select Media Server App and change this from TwonkyServer to MinimServer. You will be prompted to install MinimServer 2.2. After this has finished installing, MinimServer will automatically update to MinimServer update 263.

If you have made changes to your MinimServer configuration settings, you will need to apply these changes again.
