MELGAR, thanks for taking the time to offer your advice on posting a video! I believe I followed the steps exactly as you outlined, but got an odd result.
All of the video attachments I have seen look like a still photo of the first frame with a "play" arrow in the lower right corner. My attachment (which took 15-20 minutes, you're right about that!) was basically a blank screen with an arrow in the middle. I couldn't open it, so I assumed no one could and didn't post it.
Hopefully I won't be as frustrated next Sat and I'll try it again. Thanks again!
John
