I'm finally starting to actually use my G5 for the sort of heavy lifting it was intended for, but now that I'm doing some real work with iMovie and iDVD I've realized I'm having some rather severe crashing issues. iMovie seems to die without explanation while it's auto-opening the most recent project on startup about 50% of the time I launch it. The other half the time, it runs fine, and without issue. iDVD also frequently (maybe 25% of the time) crashes on startup as well, and now I had it unexpectedly quit halfway through the actual burn of my first DVD test disc--expensive coaster (although the half a movie that's on there looks ok). I'm wondering if other G5 DP owners have tried this with or without similar results, or if it might be a 10.3 issue (guessing not, since I didn't find any mention of that in a search here), or if it's something funky about my setup. Other than those two applications, I am NOT having any stability problems--one kernel panic caused by an old Sony analog video/Firewire converter, but otherwise not a single crash in lots of heavy use, and other applications have been as stable as always, if not better. For what it's worth, the G5 is wicked fast in iDVD when it's working. Reluctant to try trial and error, since blank DVD-Rs aren't exactly cheap.
