You need to get it all wired for a test run to see if it's the bandwidth or the encoding issue. The solution is unacceptable to most so I won't write it here.
I have the following problems with my smart TV. When i start a DLNA server (i have tried with many) on my laptop and then from the TV i start some video film it runs fine for couple of seconds and then stuck on loading for a while and then run normal. And this repeats until the end of the film. It is really annoying. At first my router was without N standard.Now i have a new one which supports the N standard but it is the same.
Do somebody used to experience such problem and what is the solution.
