"Endless communication" issue on certain Windows computers -- Details and quick-fix

If you are running a firewall like Norton Internet Security or ZoneAlarm, you may have to turn it off while you watch videos. The firewall can slow down the network packets enough that they're dropped altogether, resulting in a poor-quality connection or endless buffering.

Before you can view any videos, you will need to download and install the free RealOne Player available from http://www.real.com/player/index.html. (Note: The link to the 'Free RealOne Player' is somewhat hard to find; it is in the top right corner of the screen on the first page, and at the bottom/mid-right on the next page.)

Still not working? Let us know!
