If you convert the timecodes from non-drop-frame to drop-frame, the chapters points will be exact.
Thank you for the explanation.
Can you tell me what coefficient should I apply to each timestamp to get the correct value ?

This doesn't have anything to do with pulldown removal. The root of the problem is that the OGG chapter format doesn't have any way to specify NDF or DF timecodes, it's up to the program being used to interpret them correctly.
If pulldown removal is not concerned, I don't really understand what you call drop frames ?
