When you play Microsoft Windows Media Audio Professional (WMAPro) content in Microsoft Windows Media Player 10, and the WMAPro content requires Output Protection Level (OPL) 200 (SAP with digital output), the content plays for several seconds and then stops playing.
This problem occurs when you play the content to a device that supports Sony/Philips Digital Interface (S/PDIF).
To work around this problem in Microsoft Windows Media Player 10, play WMAPro content that requires OPL 200 to a device that does not support S/PDIF.
