At any rate, the “bad” version of the MPEG file is always having the “data” bit set, while the “good” version varies between “video”, “audio”, and “data”. Feels like Lunar is probably skipping over every non-video sector.
There’s also a format-dependent “coding” byte, which the “bad” tool is setting to 0. It has information about resolution and coding type; Lunar may be depending on it.
I’ll continue investigating, but I think I have all I need to attempt a fix now.
