    It'd help to know which trailers and using what application.

    18-24 fps here on my Mac mini Core Duo. Did you make sure to download the entire trailer first?

    Post a link to the trailer you are referring to.My Macbook plays 1080 trailers fine.

    The definitive benchmark would be the audio. Some trailers do simple stereo while others do 5.1. which takes up more resources than regular stereo.

    I have a 2.2 MBP santa rosa and loaded the 1080p trailer and did CMD+3 to fit the movie on the screen.

    I got 24 FPS playback just fine on Leopard 10.5.1.

    Do you have background processes running and taking up CPU %? Open Activity Monitor and tell it to show all processes, and sort by CPU %.

    Edit: This was also on battery power.

    I understand what the OP is talking about now.

    Whenever a 29.97 FPS QT movie is converted to 24FPS it appears a little choppy. I've seen this phenomena using just about any Mac.

    That might explain what I was seeing even at 24 fps.

    Thanks

    hmmm Now that you guys mention it, regardless of the 24 fps it still IS choppy.

    Guess I didn't watch enough of these trailers to notice it. It isn't too terrible though, for me anyway.

    It's fine on my 2.16 MBP Leopard showing on the 20" ACD.

    Was this clip ever at 29.97 though? If it was it would explain the choppiness, but given that it was film originated i can't think why it would have ever been at 29.97
