Seek issue on my mkv file

[Peaceinner]

I have a movie in mkv format in a samba server. Its bit rate is 2200kbps. I try to play it on my smart tv via network share. It can be played but I try to seek to a certain point. For example seek to 40min position. It will go back to the position before seek. Very strange. Anyone can help? Thank you so much.

Try newest MKVToolNix GUI->Preferences->Merge->Default Values. Enter into field "Default additional command-line options":
--clusters-in-meta-seek --disable-track-statistics-tags --engage no_cue_duration --engage no_cue_relative_position
(see FAQ for more info)
After that open your file and remux. Then try again.
