Pickle,
The current situation is that any tag changes etc. to your database MUST be made on the machine running Media Server.
If you make changes (or play tracks, which updates playing now, times played etc), on a client machine, the changes are NOT propagated to MS.
This can be a trap, as the client APPEARS to make the changes, but when you exit and restart MC, and re-connect to the MS, you find your changes have vanished.
I run 3 clients in my house of my server, and it is a shame that after using MC for around 18 months (I think), I have no accurate playing now info (ie. how many times I play certain tracks, last played info etc.).
Obviously, I don't play a lot of music on my server...
I (and a few others), have been waiting patiently (and will continue to do so), for this feature. To me, it would be a very good thing. For others, who make no use of Media Server, there probably soesn't seem much point.
Various JRiver staff have hinted that this is "in the pipeline", but i'm sure there are other priorities.
I'm not aware of any specific thread etc. for Media Server - maybe there should be - JRiver - Are you listening in?
