I have sync'd my trees many times without waiting for the green 'media processing' line to crawl its way across. It appears from what I've read on another post that this means all of my media hasn't been downloaded in the past. I'm now letting the green line run its course on my latest sync. Will it eventually work its way all the way across? It seems to be stuck about 2/3 of the way. Will it make up for the times I didn't let the media fully process and download all of the missing media?
