I own a LG 47LM640s, and watch my movies with Mezzmo.
After update to 3.1.1.0 (or 3.1.0.0, don't remember) I got strange trouble with my TV. LG detect started Mezzmo server, I can enter it, browse folders (if they contain sub-folders only), but if folder contain files, and TV must show thumbnails - it (TV) goes to restart.
I have no such bug with Mezzmo 3.0.x.x and new version (3.2.0.0) have this bug too.

P.S. Sorry for my English, it's not my native.
