I've prepared modified profile Movies (additional)_FR which correctly transcodes both framerates. It means smooth and in sync (audio, video).
Go to:
- Settings, Transcoder, click the button Profiles
- find Movies (additional) in the Trancode profile list
- select it and click Copy
- find Movies (additional)_1 and click Edit
- rename profile to Movies (additional)_FR or anything else you like
- overwrite the body with the attached file Movies (additional)_FR.txt
- click ok, ok (now you are back in the main setting window)
- click Devices, select your tv, click Settings
- click Files, subtitles
- select your new Transcoding profile (Movies (additional)_FR in my case)
- click ok, ok and enjoy
