Portable DVD player through TV or DVD via laptop through TV (using VGA convertor box)

You haven't said much about what inputs and outputs are available, but if the portable player has Scart or S-video out (and the telly has matching inputs), and the laptop only has VGA, you are better better off with the portable. Using a converter just add another potential noise/distortion source into the playback chain.
