The PVR addon itself sends the raw stream to XBMC and XBMC itself does the demuxing into video, audio, teletext and subtitle streams. Your problem is probably not caused by the MediaPortal pvr addon itself.
Do you only experiency problems het HD channels with 5.1 audio or also with stereo? What happens when you play a HD recording?
You could try to enable debug logging in XBMC and compare the logs for both DirectSound and WASAPI for further hints. I don't know the details behind the new audioengine in Frodo, so you might want to ask for help in the Windows Support section of this forum.
