I do not know to be honest what type the files with PES should have and mpa was the very first thing that came to my mind
The file, which I have attached, contains indeed only audio program packs. I have skipped all video packs and program stream pack header. If you need them as well I can make a complete program stream (well, not really complete, because I do not have Program Stream Map. But I do not need it for my task because I have this information from other sources).
But apart from other program stream packs, are there any other data missing in the AC3 packs themselves?
