I suspect this is the same bug I've encountered on Windows in PowerPoint 2003. (And on my boss's shiny new G4 with PPT 2004. Oddly, his old G3 with PPT 98 plays the same movies just fine in presentations.) For the jerkiness during playback, reducing the framerate certainly helps on a PC. (One of my coworkers pointed me to a Windows program called VideoLan, which makes it ridiculously easy to assemble PNGs into a variety of movie formats, with complete control over framerate and compression. It's a pretty slick program- $25 shareware I think.)
