iMovie HD bugs
See also this Macintouch posting. I've just ordered my G5 iMac with a 400GB SATA drive nad I'm getting ready to use iMovie 5 (after some experiments with iMovie 2.x on an older G3 iBook -- that was an excellent version of iMovie, subsequent versions have been a bit discouraging), so this is of interest to me.
I hope to update a y2k web page of mine on this topic, but that may not happen until September. I found five years ago that the technology wasn't ready (at least for me), but we've come a long way since then.
