Weird Encoding Results

[doomleox999]

Hi everyone, I'm having trouble with some files I want to encode with MeGUI. The thing is that the results' duration has 10 extra seconds and the audio is out of sync. I suspect the unusual frame rate (23.810 FPS) has something to do but I'm no expert.

I put here relevant data that MediaInfo tells me about one of the original files and after that the data of the encoded one.
