Resolution not accepted by TV

[effemmeffe]

I have this episode, mediainfo says that it is at 25 fps.
In my configuration I have the GUI running at 24fps.
Everything goes well but this episode: every time I try to play it my tv says that the resolution isn't valid.
If I change the GUI resolution to anything else than 24fps and I play the episode then the video is reduced at 1/4 of my tv screen.
Any idea?
