I just downloaded the entire BBC Planet Earth series in 1080p, and I just got a 30" Samsung 305t. Needless to say, I'm a little stoked to check it out. But good ol VLC keeps choking and seems to have a little low of a frame rate while playing. The stuttering gets unbearable on high-bitrate vids. I've got a 2.8ghz 8core Mac Pro and a Geforce 8800. Is there any other player that plays exotic h264/mkv/ac3/etc videos but might run better? VLC seems to run at almost 100% CPU, and I don't think it can use multiple cores. Oh yea, I've tried mplayerx or whatever, and that QT plugin pack that begins with a "P" lol. They all basically have the same problem. Thanks Any help is VERY much appreciated...I have a $3000 computer that you can make films on, but I can't watch them. Yet a $300 PS3 can lol.
