Under Windows 10, I have an .mkv file that plays properly in VLC Media Player with video and sound. However, when I try to open it for editing in Movie Edit Pro 2015 (Version 14.0.0.160), I get an error of "Error 0x3002: syntax error in mkv EBML, no seekhead found"
When I view its components in MKVToolNix it shows that the video has a codec of AVC/H.264/MPEG-4p10 and the audio has an unidentified codec.
I am willing to upgrade if that will solve the problem.
