Jp youtube don't have a limit down load it to your computer and then down load it to youtube some times it will have a glitch and that's how I do it. OH make shure you use the right format.
Irwin, as you may know, I purchased an Imac and use Imovie, an extremely user friendly program. I'm not having any trouble pulling the videos from my camera's memory cards and making movies. The program even has a "share" feature for uploading to youtube.
Thanks for the feedback.
