The frames are "dropped" when playing back the movie because you system
isn't fast enough to decode all the frames in real-time.  This can either be
due to processor decoding performance or harddisk data-rate limitations.
Either way, the only way around this (other than getting a faster system) is
to use a different codec.  If you have G3 at 500 MHz or more, you can for
example get one of the free MPEG-2 encoders (encode to VOB!) and then use
the DVD Player (or QuickTime with the MPEG-2 plugin from Apple) to play it
back - it will use the accelerated decoding functions on your graphics card
and that way you should be able to view movies up to 720*576 at 25 fps or
720*480 at 30 fps, which equal PAL and NTSC DVDs respectively.

If you have a Mac much older than three years, you will more or less have to
stick to lower resolutions or reduce the framerate...
