    Still fiddling around with my new PB/1.67/1gb/100gb/128mb 15"

    However....

    I seem to remember from a few years ago, during a brief spell with a Pb/867 15" (last Tibook) that the DVD playback was a little choppy. Now with my new TOTL pbook, the playback is still a little choppy. Is this just the way it is?

    I've never had a problem with DVD playback on my Powerbook. (maxed 17")

    Are you sure it's not just the disc? (try more than one)

    If you're playing PAL DVDs, then they're almost never be smooth, as they run 5fps slower (although higher resolution) than NTSC. It's usually not a problem if the film was shot at 25fps instead of 30, but most aren't.

    My wimpy lil' 1.33 GHz with 768 MB RAM plays DVDs without a hitch, to the internal screen or to an attached TV.

    Can you maybe give more details about the choppiness: how, when, what, etc.?

    When I get choppiness sometimes even on my standalone DVD player, it usually turns out to be a scratch/imperfection on the DVD itself ...

    No problem with dvd's here, infact, I've been know to be doing several other tasks while playing a dvd, when i have my pb hooked up to an external monitor.

    My PowerBook G4 1.67 GHz 15" 64 MB VRAM plays DVD movies perfectly. I've had no problem with DVD playback on the lowly Rev A iBook G4 1.0 GHz (256K Cache) that it replaced.

    Actually film is(was?) usually shot at 24 frames a second and then converted to 25 or 30 for PAL or NTSC as needed.

    How do they do this? Duplicate every 24th(PAL) / 4th(NTSC) frame? Or just add in extra frames (a la Fight club ;) )

    Really? I thought these days they just shot at 30fps to make things easier. Either way, PAL is very "juddery" compared to NTSC, especially on horizontal pans. (but then it's generally got much better colour and is higher resolution)
