Enable Extended Window Media Audio support (Speaker Configuration)
When enabled, Windows Media content is allowed to play at 24bit/192khz (if the media actually contains such quality) and specify the speaker configuration (see below).

Stream Windows media content using Windows Media Player ActiveX control
When enabled, Zoom Player uses the Windows Media Player ActiveX control instead of DirectShow to play MMS and RTMP streams.

Use AC3Filter as a post-processor for DRM Encoded Windows Media Streams
When playing DRM encoded WMV files, Zoom Player Home MAX can use AC3 Filter as an audio Post-Processor (can be used to convert Windows Media Audio to AC3 for digital S/PDIF output). This requires AC3 Filter v1.01RC5 or newer and the AC3 Filter must be specified to accept PCM audio connections.

Use Windows Media Audio over S/PDIF (Requires a WMA compatible receiver)
When enabled, Zoom Player will instruct the Windows Media Audio decoder to pass its audio data through S/PDIF to an external receiver. Please note that this requires an external receiver capable of decoding WMA content (most don't).

Speaker Configuration
This toggle determines how Audio Channels are mapped when playing multi-channel audio. Notice that the "Direct Out" value means that the audio is output as-is without any channel downsampling (do not confuse this with S/PDIF!).

DRM Video Renderer
When playing DRM encoded WMV files, Zoom Player Home MAX can specify which video renderer is used (some of the video renderers may not support viewing DRM encoded content).

DRM Color Space Connect
When playing DRM encoded WMV files, Zoom Player Home MAX can specify the type of connection between the WMV decoder and the Video Renderer. Selecting the Video Color Space may save a bit of CPU power, fix contrast-range issues and possibly even correct some color tinting problems. Only use this interface when experiencing video issues with DRM encoded content.

DRM Audio Renderer
When playing DRM encoded WMV files, Zoom Player Home MAX can specify the audio renderer used when playing DRM encoded content.
