i am noticing that people are complaining about bravia led not playing mkv files. So here is a guide on how to play them.
1.download tsmuxer gui..it's a freeware.
2.add the mkv file u want to play.
3.if u select the video track there is an option change level..if it is greater than 4.1 change it to 4.1.
4.now in output select m2ts muxing and point the output to a destination folder and click on start muxing.
You can playback the output file from your usb drive on bravia.
So don't just buy a tv on the basis of playing mkv files..choose tv with best pq and most important what you like.
It will take about 2 min if u are muxing 2 gb file..and so on.
Bravia can read exfat(where file size support is unlimited),fat32,fat16(file size support 4 gb, disc size support 32 gb).
pls post if you are having any problem with playback.
mkv is a container and m2ts is also a container. This application only change the container.. Doesn't reencode the video..so there is no huge cpu requirement.
