Well, our current rule is, that we now always take the "Format" tag from mediaInfo 1:1 (see examples above)
This was the best approach for the last 3 versions of mediaInfo, always having the same consistent name.
(Except for DTS and TrueHD, we have some special handling for sub formats)

Problem is, that it changed quite hefty in recent versions, and while one format might look good, it doesn't for some other.

Although the E-AC-3 with dashes does look uncommon, i'm unsure if we should change it.
I see, that with previous versions of TMM, we ALWAYS removed the dashes... but that doesnt look good for others...
Like DTSHD-HRA...

So... what should we display?
A technical codec name?
with or without subformats?
maybe a common commercial name?
DTS? DTSHD? DTSHD-HRA? all the same...
AC3 even for EAC3, because only subformat?
[...]

Have no idea how to solve that... or AC3 can be the only exception without dash....
but we really do not want to implement some mappings (although this would be the only solution to fit all users)
