I know this is an old thread but I'm having some trouble splitting the Courage the Cowardly Dog 1080p episodes that @DawnShadow. uploaded. Some of them split perfectly but others start a few seconds ahead even though I put in the correct time.
I'm using MKVToolNix and splitting after specific timestamps. Reading what @kinglir28 said I need the correct frame which I'm unsure of how to get.
I even tried this app Banana Split with hopes of it working but it didn't do anything.
I use Kodi so having these kinda shows split would be a godsend!
