Thanks for the prompt reply. Actually, I don't want a C/S setup. This would require the server to be running and files to be transferred across the network when I am using MC. I just want instances of MC on multiple devices to stay in sync. If I make a change on one device the change happens on all devices. With cloud services like DropBox, I'd think this would be more common. Countless applications now work this way using cloud sync built into the app itself.
If I am at home on my HTPC, my experience with MC could be the same as when I am traveling with my laptop not connected to any network. For example, if I change the sub-media type on the HTPC to change where I would find a file in TheaterView. When I open my laptop later, that is where I want to see the file.
My media files are all in a DropBox folder and the local copy of that folder is what all instances of MC are using. If I add a file on one PC it shows up a few seconds later on the other PC. If I change a tag on one PC, the change does NOT show up on the other PC. I had all my instances set up per your step 1 & 2. The media files are identical on both PCs.
I have to conclude that the tag is NOT actually being written to the media file. Seems to be written to a Sidecar only. DropBox notifies me of the Sidecar file changes -- sometimes. But, the second PC does not seem to notice the change. It still shows the same tags, regardless. I even tried the Tools>Library Tools>Update Tags from Library on PC1 and then Tools>Library Tools>Update Library from Tags on PC2. The tag does not change on PC2. Is this a bug, because it does not seem to be doing what it says it is doing.
If this is a design limitation with MC, my idea is to put the library in the DropBox folder also. Is it possible to move the Library away from its default path and tell each MC instance where to find it at startup? This way, DropBox can keep the Library in sync and all MC instances will use the identical copy.
Thanks for your help. I only have a few days left in my trial and I am hoping MC will work for me. If not, maybe in a future version you will consider cloud sync as a feature.
UPDATE: I went ahead and experimented with creating another library and putting it in a DropBox folder. Then I also switched the second PC to use the same library. Seems to work so far.
