I was having problems rendering mp4, (h264, aac), files with my PBO. After re-encoding several files to get them to play,(h264, ac3), I discovered that it was the aac audio that was giving the PBO trouble. The PBO sees the mp4 file as an audio file.
If the original troublesome mp4 file is demuxed with Mkvmerge and the audio is saved as an mka audio file, video as an mkv file, and then remuxed, the file will play in PBO with no problem.
My question is why would doing this make any difference seeing as how nothing is changed but the container (mp4 to mkv)?
