real one player

http://www.realnetworks.com/ (except that if you're looking for a version for your phone, then it either comes as a built-in app or not).

I have the realone player in the 6600, but a m8 sent me two trailers, one for the spiderman movie and one for the holly valence movie.

It plays the movie but not the audio, a warning comes up when it starts,

Is there any update for realone player or any good video players that would play most movies?

I presume its just a audio codec it needs to play it.

i cannot seem to find anything about a player for this phone.

any help appreciated
