You will be able to view videos adequately from a 56 Kbps connection, though as you imagine the quality will increase with higher bandwidth. For optimum quality use a 500 Kbps (0.5 Mbps) connection. Note that even with a fast connection high traffic on the Internet may reduce video quality.
The most common cause of a pause or stop is Internet traffic congestion. The videos at Nobelprize.org are provided for several bandwidths and the player negotiates with our server on what quality can be transmitted with the current bandwidth between us. Sometimes this is not sufficient or there are fluctuations in the available bandwidth that causes too little data to reach the player. When the buffer runs out the video pauses until enough data is received.
You don't need anything additional to view the videos on Nobelprize.org. They should run natively in all modern browsers and mobile phones.
Most of the documents featured on Nobelprize.org do not require plug-ins, though you will be appropriately informed should a plug-in be required. For more information on the types of plug-ins you might need on Nobelprize.org, and on how to download them, visit these pages:

On some networks (often corporate networks) video transmissions may be blocked. If you cannot see any of our video clips, you may want to contact your network administrator to see whether a security firewall is blocking video transmission.
Currently we provide the videos in Flash.
