    Does anyone know why 1080p video runs slow on my late 2008 Macbook Pro (lowest end + 4 gig of RAM), yet 720p runs just fine? I'm using VLC for both...I mean, 720p is still great quality, but I would like 1080p for certain things...

    what do you mean by "slow"? Does it slow your computer down? If that's the case, it's quite normal, especially for high bitrate video files. BTW, what is the bitrate of your video?

    Are the 720p video and the 1080p video using the same codecs for audio and video?

    No, it's not slowing the computer down, it's just lagging a lot, for instance, with Planet Earth, the beginning sequence which is supposed to be a smooth lighting up of the earth is really jumpy.
