A couple of things you can do:

  1. Click the Pause button (||) for a while. This pauses your playing while the download “catches up”. Go and make a cup of tea, then come back. It should be downloaded by then – click the Play button again, and it should play without stalling.
  2. Select a “lower resolution”. You will see at the bottom right of the playing screen, a small “drop down box” with a number next to it… something like 720 perhaps. If you click the little arrow, you will see a list of different resolution numbers. The lower the number, the quicker it will download, and thus reduce the “stalling”, but the lower the quality of the image.
    The higher the number, the better the quality, but the longer it will take to download – and you may  need to use trick (1) above.
  3. If you are still having trouble downloading files, you may want to check your download speed at www.speedtest.net. If your download speed is less than you are “paying for”, contact your Internet Service Provider and complain.
    Make sure if you have an ADSL service, that you have “Line Filters” on any phones or faxes you have connected. Your computer connection is the ONLY one that should NOT have a Line Filter installed.
