Being curious and checking, all I can tell you is that the uploader apparently had a problem when he uploaded the video resulting in the audio being a bit out of sync.
If Kaichou wa Maid-sama! is out in english (animax) dub on various websites, why can't this series?
I know the Animax dub only aired a few times and is not really popular, but I can guarantee that there are some torrents of the series out there on the internet.
Well, I don't know what to tell you on why the Animax dub of Hayate no Gotoku! isn't on any of those sites, but if you really want to watch the Animax dub of Hayate then you can try Youtubehowever they only have a few episodes and the audio is not properly synced. If you want the whole season then like I mentioned, you can download it from a torrent.
I watched every episode in English at www.dubcrazy.tv
