As the title says, I need a program that will show me the time codes of frames that I can copy/paste into the MMG chapter editor. AVIDemux won't load my MKV's properly, I've been having to remux them into .ts files, and doesn't show the correct time code (+.04ms), among other bugs. I've tried an AVS script using FFVideoSource and VirtualDub but I can't skip to keyframes that way or search for black frames. The FFMPEG plugin for VirtualDub will let me skip to keyframes but won't let me search for black frames, is unstable and liable to crash.

Are there any other programs I could try?
