This is why many use a better media server. One that can transcode on the fly to help smart TVs deal with oddly encoded content. Unlike your PC, only a single percent of encoding is supported. On top of that the bit rates are also limited.
I've looked at good and bad files before and always find something different. I use tools such as the 5 noted at http://www.ghacks.net/2009/05/18/video-inspector-displays-video-codecs-information/ as well as WMP, VLC Player and others.
The problem is the encoding. To consumers they won't hear this. They often flame on about it. Well discussed area with some clear answers. Mostly unacceptable to your average consumer.
I have Samsung BD-H6500 blu-ray player, connected to my DLNA.
Everything works fine, my local media server content is browsable in the player.
But, some video files behave in a strange way.
For example, I start watching a movie, it goes well for few minutes, and then it spontaneously jumps to the beginning and the movie simply starts over. It can go well without any problem, when I watch it next time. I really have no idea what is going on.
The same story is when I watch a movie via Plex. Some video files also behave the same way.
Some video files always work normally, without jumps. But, I cannot notice any difference between them and the problematic files - the same format of video/audio, size, etc.
What could be the problem here?
It is definitely a problem with player, because I also tried to play a problematic file via USB there, and it behaved the same way.
If there is no solution, I will have to get rid of the player.
