Just upgraded from Movie Studio Platinum 14 to 15 in the hopes of getting some better performance and bug fixes.
I use ShadowPlay to record some of my games and I split the audio tracks from my mic and ingame.
These neatly show up as two seperate tracks in the editor. In MSP 14 I had the problem that the program would freeze while importing clips with multiple audio tracks. So to fix it I had to toggle some settings at the cost of performance.
Now with MSP 15 the first clip that I import will work just fine, but with each one after that the ingame audio track will become silent mixed with intervals of audio stutters, small audio segments from other parts of the timeline and sounds from my mic.
It seems random what sounds it chooses to play, even changing what gets played after repeating certain segments.
The audio track from my mic works just fine. Both tracks used to work in MSP 14 as well.
Disabling the So4 Compound Reader makes the program crash while importing clips.

Please help, thanks!
