Impossible de lire une vidéo sur site

Bonjour,
j'ai mis des vidéos sur mon site au format .mp4 mais le site en lis que 2 sur 5. Avec le même code.
Les codes en gras ne sont pas lu. Je n'ai pas mis toute le code.
Mais la premier vidéo et la 2eme tienne moins de place que les autres. Il le lit avec QuickTime player.

Le même code source, mais les vidéos ne sont pas toute lut.
Devant ce problème énervant, j'espère que vous pourrez m'aider.

Merci d'avance.
