High res video on n6300

First of all, sorry if im in the wrong group here and will please
redirect me if that is the case.

I have reasently bought a nokia 6300 and have done some experimenting
regarding video playback, however one or two questions has dropped
into my mind.

The nokia 6300 has a 320*240 px tft screen. Supports mp4(well it
should, im actually not sure) h.263, h.264, aac, etc. But still i cant
get it to play 320*240 px videos.

If it can't be done it can't be done, but if anyone has actually done
it, i would very much like to know how. The hardware certainly allows
it, allthough it might not be "powerfull" enough.

Allso i would like to know exactly which restrictions this phone has.
fx. regarding fps, resolution.

Basicly i want to know it all.

Hope you can help.

Regards
