All new movies are showing up twice in the media list. Not sure if this is related to the Beta or just simply since I have both installed. I'm only currently running the beta version as show below.

This is a known issue with libraries that make use of collections. Are you using collections and/or nested folders in your scan folders?

Negative, I have no collections.

Folder structure is as follows.

\\Thetardis\media\Movies\movie etc..
\\Thetardis\media\TV Shows\Show\Seasons etc..

Testing results for folder access
This shows that structure

Hmm, no odd symlinks either I presume?

What happens if you do a full cache refresh (Shift+F5)?

Nope no symlinks either..and the shift + f5 does fix this issue, however...just to test.. I moved the movie... removed it from MCM and had it re-detect it.. found, added and shows up twice.

Are you saying there's an issue with auto-scan, then?

After this testing, I would say yes.. I guess I didn't know the application well enough to call it that in the first place.

You aren't the only one to report problems about auto-scan in the new beta. I'll have to do some more testing, looks like!
