Thank you once again! I'm sure someone in charge for coding plugin connection code needs to know about these things happening.
Also BorisFX 9.0: Pixel Fixer plugin strobes in program monitor sometimes returning "Bfx error code 25"
I have noticed that problems happen more likely if you use Quicktime Cineform source footage or DNxHD MXF.
Maybe these MXF read errors in CC 2014.1 have something to do with it.
As i said, i can send a small, simple but glitchy project file with two sources to you or your coding team,
so they can easily reproduce all these errors that i'm getting
