GUI becomes slow/unresponsive after opening some files

Looking at the debug outputs,...

It's not the time code extraction, it's the mplayer analysis.

For test1:
Hybrid looking for video IDs:

2020.02.19 - 10:08:14_Windows 7 Version 6.1 (Build 7601: SP 1) (64bit)_2020.02.17.1 - level 9: MPlayer AudioAnalyser calling: "D:\BIG APPS\Hybrid\64bit\mplayer.exe" -v -msglevel identify=6 -nolirc -frames 0 -novideo -vo null -ao null "Y:\New\TGDPC8~2\TGDPC8~2.MP4"

outputs tons of data (lots of time codes) and takes 6 seconds.
Similar call, looking at audio id 0 with:

takes 40 seconds!

takes 8 seconds!

For test2:

no clue what happens there to cause 26 seconds delay.
Another unkown delay:

seems like whenever Hybrid accesses the Streamdata of the source it freezes.
Which is really strange, because this should only happen if either the system is swapping or a virus scanner or something similar is interfering.

I managed to reproduce the issue when forcing time code extraction on a file and then changing chapter and similar.
-> looking into it
