netflix streaming stops after 2 minutes

For over a month now, Netflix on the ATV2 will stop streaming after 1.5-2 minutes with every film I attempt to watch. This happens only with the ATV. Wireless streaming of Netflix to the Macbook Pro and the iPad2 work on the same wireless network without any difficulty. In addition, I can watch YouTube, podcasts, internet radio, and MLB.com on the ATV without any difficulty. I've reset the ATV multiple times without a change in function. Any suggestions would be appreciated.
