It seems of all the files I've checked so far,
The files that are causing problems have settings like this:
> Stream #0:0: Video: h264 (High), yuv420p(tv, bt709, progressive), 
> 1920x1080 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc 
> (default)

While the file that are running just fine, all seem to have the setting 
this:
> Stream #0:0: Video: h264 (High), yuv420p(progressive), 1912x1032 [SAR 
> 1:1 DAR 239:129], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)

Is there a way to ensure "yuv420p(progressive)" without "tv" and "bt709"?
