Be sure to look at prior discussions but let's start with MKV is nothing more than a "container." What's inside can be encoded in many ways so no one should ever write that MKV is going to play everywhere. MKV is supported but then we get to write at length about the difference of containers versus encoding.
Consumers don't want to know all this yet it matters.
And no. I've yet to find much other than "if it plays, it's supported." If it does not play, it is not supported.
Some get upset, some figure it out that these are not PCs but TVs.
I've got a Netgear Router WNDR3800R that supports DLNA media streaming and I've connected an external HDD to the router and managing to stream certain media files to my Samsung LED Smart TV : UA46D5500RR
I've noticed that there are certain formats like .mkv that the TV does not support via DLNA streaming as I keep getting the "file not supported" error. These files however play perfectly well when the HDD is connected directly to the TV.
Can anyone tell me what are the DLNA supported media types that the TV would support?
Thanks & regards
