As I have Media Browser running via Media Centre on my main PC and the HTPC I don't even end up with a consistent view.
The final straw has come in that I also have XBMC installed in both locations and that updates too and has added a healthy does of random.
I'm trying to get used to XBMC because MediaCentre is on the way out - I believe it is a pay for option on Windows 8 and that will kill it off, the downside is that the other products are just too complicated - yes they can do a lot of things but I just want my media presented in a simple interface with not too much messing about but having spent an extended period with MediaPortal and a couple of other products XBMC strikes me as the only viable alternative out there (and I'll try it again on my Rasperry Pi eventually, I love the Party Mode in the music library).
Anyway, I'm a long term user of Yamm, Yet Another Media Manager, which works pretty well but it too can have a randomisation effect - clearly they all pick up standard files from common sources and it is those sources that are changing. I've now stopped Yamm monitoring my entire collection and today I have been through and removed all automated updating from Media Browser and Yamm on both machines and manually visited every movie and corrected the content; it seems the best way to do this is to individually add the movies folder to the Yamm config and then wait for it to update (I've frequently resorted to adding
[imdb=ttxxxxxxx]to the end of the foldername (where ttxxxxxx is the id from the imdb.com site) to force Yamm to use the correct film information.
Now all of my Movies have the correct information and look great in Media Browser and XBMC.
