Since I upgraded my E8000 Serie Samsung TV set with the proper Evolution Kit (Sek-2000/XC) DLNA streaming doesn't work so good anymore. I can see a little buffering randomly and after that 1 second of the movie is missing. I think that's a profile issue, because I have no issue at all by using a LG TV. Do you think there will be a dedicated profile setting for this kind of Samsung upgrade kit?

Probably not a profile issue, as Samsung profile hardly transcodes anything, it's probably a network latency issue.

If it can help, I noticed that the issue doesn't occur streaming video files less then 720p resolution

If you're on a wifi, it'll be that. Network quality changed.
