Split DSD and DLNA
ok but you cut my post out of this one (I edited it out of the split post)
here is what is "salient" to the OPI would drop the differences of number of albums and artists, first. As the OP already mentioned, there are going to be differences depending on tagging, View set-up etc.
The number of files should, however be identical so stick to that for the moment.
if you were running Windows I'd bet it has something to do with the filepath being too long (total number of characters filename+path); often using UNC paths to NAS could bring you over the top of that limit, causing problems with playback or the files simply do not get imported.
The difference between a lettered USB drive and a 15 character NAS file path could explain this. I do not know why there is a difference of 5 files between "A" and "C", but could be iso or cue files that are not being imported via the Minim server or something like that.
However, I don't run macs often using JRiver so I don't know what or if there is a length limitation for MACos (or if JRiver imposes the WIndows one either for that matter, possible)
I'd still try and find say 5-10 files that aren't being imported from your "B" scenario and post the complete paths here. Classical music often has very long filenames anyways, if you have a bunch might want to look there first.
Thx so far. First, I completely missed the available of a MC Linux version for the QNAP. But I found I am unlucky, as I own the HS 210 and MC does not run on this version. Is this because the HS210 is not powerful enough?
So far, my QNAP is just a file server and MC runs on my MAC. I can only explain MAC-MC's behaviour on the NAS as a result of "NAS Read' issues. I have used manual import function only.
My main issue remains unsolved, but the Linux version may an even better solution but for that I need to buy a newer QNAP!?
QNAP hasn't made this available on all their models ... don't think it is a "power issue" really ... have to get on to them. Maybe you can upgrade your machine, not sure. However, as Brian inferred too above, if you have one computer and a NAS already, don't bother - use the PC or Mac as the controller/media server (and preferably as renderer too in most cases) and the NAS as just file server/big external drive. The Qnap NAS installation could be interesting if you had multiple clients, not all of which would need to be turned on at the same time. A mac or pc is going to perform much better than a NAS, especially as a controller and renderer (certainly power over price, much cheaper). External access to you network might be cool using the MC Library install on the Qnap tho.
