    I did a fresh install of Vista on my HP Pavillion dv6500t and noticed that with all the latest drivers from intel and latest quicktime player from apple installed, that I still wasnt able to play 1080p quicktime trailers smoothly. However interstingly enough, my cpu utilization was only 40% when playing them so I knew CPU was not the problem. (I have a c2d 2.0ghz and 2gb ram). I went into the Quicktime player, went to Quicktime Preferences, and unchecked the option to "Accelerate video with Direct3D" and now my 1080p quicktime videos play flawlessly even full screen with only 60-70% cpu utilization. Just thought I'd provide this tip to those of us with less than stellar video chips.

    Or you can use a decent Software codec and player, and play stuff 1080p on 1,4GHz C2D's.

    Try using another driver. Maybe an older one. That usually does the trick. That happened with my dedicated 8400m gs with XP. I used an older driver, and it ran the 1080p videos from quicktime smooth as butter. Even 3-4 of them at the same time played smoothly. So try different drivers for it.

    Try uninstalling it and run Windows Update if you have Vista. If Microsoft has one for your IGP, then use that.

    no point in playing 1080p when the max width is only 900.

    Which 1440x900 WXGA+ screen are you talking about? The dv6500 only has WXGA.

    When 720p has to stretch out in order to fill the WXGA+ screen, I'd rather have the other way around, where 1080p video would have to scale down. I think it looks better.

    Say you had a dinky 15" VGA LCD TV--a QVGA video fits without scaling, but it wouldn't look nearly as good as XGA, which still has to scale down.

    There's a huuuge difference from scaling 320x240 to 640x480 and scaling 1280x720 to 1440x900.

    The first situation is scaling a very low resolution to a 4x higher resolution, while still being quite a low resolution.

    The second on is scaling a high resolution video to a slightly higher one, whilst being encoded with a codec that scales well at highbitrates.

    There will be no difference on a WXGA+ screen. Hell, there's not a lot of difference on a 1080p Screen.
