Let see if doing some trouble shoot might help before we really call this a bug huh?

Yes I agree the DLNA share need some work
I have a LG 55LN7600 , if I share movies using the Win7 media server, when I go to "all movies" all the movies share through the computer are available.
However, movie files shared using the router media server are not available. I have to go directly into the connected device link to view them . In addition, if I try to fast forward a movie, I get a invalid file error.
Looks to me the router software could be update to meet standard connectivity for media streaming.
I also an ST600 and Samsung BLU-RAY, I will check those to see if I also have problem
