    i was wondering this, because i looked at some HD trailers, and i was able to play 720p fine, then 1080p lagged and skipped a bit. also, i used quicktime, and when i hit the max button, it filled the screen up more, but im not sure which is actually the 720p signal (sorry if thats confusing). like, is the maxamized version the real 720p, or is it the one that quicktime defaulted to? ill try to get pics later to show you what i mean

    *i have the e1505

    what is the resolution on your screen? I'm sure that it can play 720p video fine though. If you just open a 720p file in Quicktime the file will be at its native Res, if you do maximize it streches it out. 1080p will not fit on your screen (you need 1920x1200 for 1080p) but if you open a 1080p movie and then maximize it, it will shink it to fit your screen.

    Also if you are trying to play with inferior codecs, that will slow you down too. In the coming year, better and faster codecs for high res video will be out, I doubt a core duo will have any trouble decoding them.

    720p = 1280 X 720 in progressive (i.e. up to 60FPS)
    1080p = 1920 X 1080 in progressive (i.e. up to 60FPS)

    Correct me if I'm wrong, but WSXGA+ is 1680 by 1050, therefore a 1080p video will be downscaled on your screen.

    Also high definition video requires a lot of bandwidth and decoding abilities, so the CPU and GPU are both worked hard. Perhaps your GPU is the bottleneck in this situation, causing the stuttering.

    I think the 1080p probably lagged because of your internet connection.
