If you are using HXClientEngine object to drive the renderer, defining 
HELIX_FEATURE_VIDREND_UNTIMED_DECODE is not enough since the packets 
delivered to the renderer will be timed and the un-timed decode needs to be 
activated via IHXUntimedRenderer::SetUntimedRendering.

You'll need to override the audio device with own implementation 
IHXAudioDeviceManager::Replace to drive timeline at desired speed.
You can trigger the untimed decode by issuing 
IHXUntimedRenderer::SetUntimedRendering on any renderer that supports this 
interface.  You'll need to enumerate all sources and all streams to get to 
the renderers: IHXStream::GetRenderer

To pass the time-stamp to the surface, add new API and use it from 
vidrend.cpp on Blt if the API is available.
