The obvious answer to your problem is that a DVD player is mainly intended to play, well, DVDs, and if it has some MP4 support (like they had DivX in the past) is only at the mercy of the manufacturer, and this includes also the features and the options.
I believe a BD player would be a better choice than a DVD one, although not perfect, for the same reasons.
