MKV playback problems with WD passport connected to WD LIVE TV

If i play MKV files through network it works but when i put the same MKV on my WD passport and try to play it back it freezes after 5 min. Tried different MKV files

Can anyone help?

Have you checked your drive from errors? If the movie frizzes when played from the Passport…

yes i did, avi plays fine but not mkv files, only through network
