I'm using a MacMini 1.8GHZ, 1 GB RAM, to try and play back a 1080p WMV using VLC player (I also have Flip4Mac installed). I keep getting errors that it's dropping frames and there's no sound. Is this an issue with not having enough CPU? Is is it a driver/player issue? Has anyone been able to play back a 1080p WMV on their mac mini fine?
