Symptoms

When you use Windows Media Player 12 on a computer that is running Windows 7, the Play To feature does not work in the following scenarios.

Scenario 1
  • The computer has two or more network adapters. Additionally, at least two of the network adapters are on different subnets. For example, you have an Ethernet network adapter that connects to the Internet, and you have another Wi-Fi network adapter that connects to a local area network.
  • You try to use the Play To feature to play media on a digital media receiver (DMR) device through the Wi-Fi connection.
In this scenario, the DMR device receives an invalid URL that contains an incorrect IP address.

Scenario 2
  • You enable Wi-Fi Direct concurrent mode on the computer. This mode lets Wi-Fi client mode and Wi-Fi Direct mode coexist.
  • You try to use the Play To feature to play media on a DMR device through the Wi-Fi Direct connection.
In this scenario, the DMR device does not play the media successfully. The device plays the media if you enable only Wi-Fi Direct mode.
