I've already done searches of threads here and found random threads pertaining to mostly older versions of iDVD....so..... I have a video I made in iMovie (newest version) with footage imported from my DV cam. I sent this movie to iDVD and have had nothing but problems. I have successfully burned two movies prior to this one that I am having problems with. The only difference that I can tell with this one is that I've used more transitions/effects/titles than in movies made before and I added some Crucial memory bumping me up to 1.25gb on a single 1.6ghz G5. I've burned three DVD-R's with this newest movie and on the first two the video stopped just a minute or two before the end of the movie but the audio kept going. On the third I tried to burn, it did it's thing and resulted in a buffer underrun error and appears to have only burned maybe half of the movie. I haven't watched this one yet to verify but it appears the "burn" on the disc is half the width of the other all-but-completed discs. I've tried different combinations of burning at "best quality" or "highest performance" in the preferences of iDVD. I've deleted encoded assets. I've turned off my power saving things in the Mac's system prefs.... I'm assuming it's either the memory or the bulk of transitions/effects in this movie... Any thoughts?
