MPlayer IS the internal player, isn't it? I have to say, though,
judging by what you said about the aspect ratio being set to 2.35 on
that file, the aspect ratio is set in the file, and is wrong. Your
aspect ratio should read 1.78 if it is true 16:9.

Are you using the "playback recordings" option, or are you using
another option? Because doesn't Myth have a special option for
playing back video files from sources other than internally created
videos? I'm pretty sure that if you were using that option, Myth
wouldn't enforce the aspect ratio settings like that.
However, I think I see the problem. This came up with before on the
MPlayer mailing list. Try to find your media playback options. Look
for any 16:9 options for the aspect ratio, and change it to -
monitoraspect instead, that might fix the problem.
