Just to check those specs I went to http://www.samsung.com/us/video/tvs/UN46D6000SFXZA and downloaded the manual.
Remember that what plays on USB is not assured to play on DLNA. Many were not aware of this fact.
I'm reading "User Manual
Mar 23, 2011" does write "Playback of various video formats (DivX,XVID, MP4, 3GPP, AVI, ASF, MKV" but that's not telling you the FULL story.
Since AVI and MKV files are CONTAINER FORMATS it is very easy to have files in those containers that will never play.
But here's the kicker. m2ts is never found in that manual!
Connected my new UN46D6000 via wired 100mbps connection to my Windows 7 Home Premium system. DLNA is configured and works fine for pics, MP3s, AVI/DivX...
However, trying to stream my AVCHD videos (.m2ts) created by my HD camcorder (Vixia HF10) does not work and gives the error message : 'unsupported file type' for all files.
Putting the .m2ts file on a thumb drive and connecting to the TV, it works perfectly and looks awesome. Specs for the TV says is supports .m2ts files.
The main reason I bought this TV was for the DLNA/m2ts support and it doesn't work. I also did a firmware update, still no luck.
Any thoughts out there? Thx in advance.
