Not a problem... I'm just glad enough to not have to explain the whole
thing for the third time in about a week.

Actually, the problem is most likely not the MP4 container but the but
the x264 video; I don't think that MP4 takes significantly more to demux
than AVI does, but x264 certainly takes more to decode. You'll probably
need to transcode the video (with a high bitrate - something around 1800
is probably the minimum if you don't want to lose quality, I
experimented in detail once) in order to play it back at full speed.
