Sorting issues

Infuse 5 Pro sorts my movies from a DLNA server in an odd way. It shows about half of my movies from A - Z, then starts with A again and shows the rest of the movies to Z. Any idea what is going on? All movies are .m4v and I have Infuse set to sort by Title.

When I look on the hard drive from a computer everything is sorted correctly.

Often when connecting via DLNA the DLNA server will play with the file names that are shown to Infuse.

If you connect using SMB or one of the other protocols it should be correct.
