The "Masters" files of my movies seem not to be accessible when I try to import them to WP. For some reason (could it be that the iPhoto library in question is on an external hard drive?) is greyed out when I try to access it via the WP uploader...Thoughts?
Ah, that could explain it. You would need to plug in the external hard drive if that's where the original video file is located.
it doesn't look like I can upload screenshots to this thread
When you upload the image to your Media Library, you can click the Edit link for the uploaded image, then copy and paste the File URL here.
already using the latest version of Chrome so that's not it.
How about Mozilla Firefox?
What's weird is that now I am not even getting the "this video is being processed"
Hmm, what's the Media URL in your dashboard?
Also, what's your internet connection speed (download and upload)?
