Problems with video codecs?

[sread]

While waiting a long time for my 6230, I've started downloading movies and converting them using the nokia multimedia player... For some reason, on playback there's time delay between the Sound and Video...

Is this a problem unique to me, a problem with the file conversion or a problem with the player afterwards???

Is there better free software out there to convert avi, mpg, mov files to 3gp?

I can't watch films that look like they've been dubbed!
