Hello Michael,
Thank you for the reply, and your help. The QuickTime AMA replacement plug-in makes perfect sense as to the root of the problem, which is causing me more than a few grey hairs! In researching the problem, I did see some recommendations to relink the media, and that makes the most sense to me, but maybe because I’m a newbie, I can’t quite seem to figure out how to do it. For example, when I did the steps you suggested (select clips, select sequence, right click), I do see a “Link files” option, but it’s greyed out and un-chooseable. I haven’t seen a “relink to selection” option. Could you explain a little bit more how you do it?
Thanks again for all your help so far.
Alberto
