How do I upload to the Multimedia Community? I put together my first five minute home movie masterpiece and my first upload failed because it was in .MVP format. I think I converted it (by trial and error) to *.mpg and tried again. All seemed to proceed ok but it went on for ever, with a small 'clock' rotating indefinitely. After about an hour I clicked something on the screen (I don't know what) and the whole process stopped.
