Comment (by kn100):
This is affecting me too on the latest build (May 13th.)
The first file is an AVI created with Beepa FRAPS - A screen recording
application
The second file is an MKV which was created by running the above AVI
through FFMPEG with libx264 and libvorbis selected.
Setting the SAR seemed to fix it for me. I have included a link to the two
test files I am using below.
Here is my initial command, which fails.
