    I've got a HP Pavilion dv6000 notebook running Windows Vista Home Premium. It's got an AMD Athlon 64 X2 Dual Core 1.7GHz Processor TK-53 with 2GB DDR2 667MHz RAM. The graphics processor is nVIDIA GeForce Go 6150. I get very choppy HD video playback in full screen mode with Quicktime, audio works fine. Like if I try to watch a movie trailer in HD & view it in full screen the video playback is quite far from smooth-I generally use the Apple movie trailer website which loads Quicktime separately for HD videos. However, if I 'maximize' the window but don't view it in full screen the video plays perfectly smooth. Or, if I save the video to my computer & then view it with VLC Media Player or Windows Media Player, it works perfectly fine. This is with all the resolutions; 480, 720 & 1080. 1080 doesn't work well with Windows Media Player though, only VLC Media Player is able to play that smoothly. Why is this happening, how do I fix it? I've already tried the 'safe mode (GDI only)' option which didn't change anything.
    One thing confuses me, should I have the latest drivers according to the HP website or according to Windows Update?

    Honestly, I think the problem is Vista and the video drivers. Update both to the lastest versions. ATI had a similar problem too, but I don't know if their issues were solved.

    Get your drivers from www.laptopvideo2go.com, as the HP ones suck and are older.

    Well, my computer is up-to-date according to Windows Update & according to the HP website I've got the latest video & chipset drivers installed. Maybe I can try re-installing them or something. What do you reckon is the best of way of going about re-installing the chipset & video drivers? I am not able to find the chipset drivers in 'Programs & Features' in Control Panel so I don't know how to uninstall the chipset drivers.. I can only see 'NVIDIA Drivers'.

    Edit: I installed the 165.01 drivers from the laptopvideo2go website & still no improvement. Any ideas? Try a different driver from that website?

    Ok so finally I found a solution for this right here with the "Quicktime Alternative"-use Media Player Classic to stream the video-until drivers fix the issue properly I guess.

    Quicktime in itself is not a very good video player. Add on the fact that you are using Quicktime for Windows, which is even worse, and probably doesn't have hardware acceleration support, you get choppy playback.
