I don't know what you consider high resolution, but I just tried a
640x352, 29.97 fps, divx encoded video. It played with no problems.
My iBook has 32 MBytes of video RAM, but this is not really relevant.
Now, I have experienced poor video playback in the past, but the problem
was not the iBook, rather it was one of the following:
(1) Inefficient software. I use mplayer, which I compiled myself from
source. Vlc and xine (installed from the ubuntu apt repositories) are
definitely inferior, and often have poor playback.
(2) Audio problems. I have no idea why, but for some reason, the
mplayer OSS output driver works better for me than the ALSA output
driver. If I use the ALSA output driver, I sometimes get dropped frames.
(3) Poorly encoded videos or videos encoded with a codec which has poor
(or no) support under linux-PPC.

Larry
