I've used mediaplayer before but I was wondering if it was because the file was so big ,593.5MB, or if I should do something with the sd card ?
Mediaplayer doesn't seem to play movies at 640x480 very quickly if you enable fullscreen scaling. I figure it makes more sense to feed it a 320x240 movie and run Mediaplayer in the lower resolution mode by turning magnification on. It sounds like it's already on, because you're already seeing a "Please wait..." message as it changes video modes.
I'd try playing small movies from your card. If that works, maybe it is due to filesize (is it scanning the file to compute time? is the movie encoded with an index for searching?). If possible, try encoding the movie differently and see if that helps. If that doesn't work, try playing small movies from internal flash.
