WD Elements Play 1 Tb doesn't work with any mkv file

Why my elements play doesn’t work with any mkv file, 24-25 fps, when on manual it work up to 30 fps.

For some films on dvd/iso,  on blu ray/iso  and mkv files there are sometimes microswitchs (microscatti) during the vision, especially when elemets play  works  from an external hard disk usb.

Is there anybody who can help me?

Thanks

Stefano

Hi there, just because a file has an MKV extension and 30fps it will NOT play as it should…

What about the codec of the MKV, the bitrate and the resolution?
