Hi, i have a desktop mac with a G3 processor; its an old man. I recently downloaded a film, but realplayer has real trouble playing it. I've watched films before on my mac, i know it can work but i guess it has to do with the dimensions of the film im watching or something like that. VLC plays visual no problem, but it has no audio whatsoever, and i have no idea why. I usually just sync the visual of VLC with the audio of Realplayer if this happens, but only ever for short videos in the past, I dont think my old man can handle this for a film. Do i need a special codec or something? DJO player and Quicktime take one look and keel over.
