[QUOTE="htpcoz, post: 58810, member: 13987"] I know that AC3 is detected, based on the Status display of my TV (the TV is the SPDIF decoder). When I connect to a channel without an AC3 PID it always displays "ProLogic", whereas when I connect to a channel that does broadcast AC3 then the TV shows "DolbyDigital". I've also checked the Nvidia properties, and it indicates DolbyDigital when my TV does, and MPEG when my TV indicates ProLogic. The interesting thing is these dp appear to be at odds to what the MP OSD says. In MP the list of available streams in the audio OSD indicates that the "english" ie non-AC3 stream is the active one, even though all other indications lead me to believe that AC3 is in fact being played. If I try to change to the AC3 stream then all hell breaks loose and MP locks up (that appears to be a known issue tracked by another thread). When I go into channel setup and set the AC3 PID to 0 and select the channel the MP2 stream is played, in the logs I see the following: 14/06/2006 10:21:44 AM Navigator:ZapNext Seven Digital->Nine Digital 14/06/2006 10:21:44 AM Channel change:Nine Digital 14/06/2006 10:21:44 AM GUITVHome.ViewChannel(): View channel=Nine Digital ts:True 14/06/2006 10:21:44 AM g_Player.Stop() 14/06/2006 10:21:44 AM g_Player.OnStopped() 14/06/2006 10:21:44 AM StreamBufferPlayer9:cleanup DShow graph False 14/06/2006 10:21:44 AM StreamBufferPlayer9: vmr9 disable 14/06/2006 10:21:44 AM StreamBufferPlayer9: vmr9 dispose 14/06/2006 10:21:44 AM 1 vmr9:Dispose 14/06/2006 10:21:44 AM VMR9: not active 14/06/2006 10:21:44 AM PlaneScene: PresentImage() dispose surfaces 14/06/2006 10:21:44 AM PlaneScene: PresentImage() dispose surfaces 14/06/2006 10:21:44 AM 1 VMR9:ReleaseComObject():0 14/06/2006 10:21:44 AM PlaneScene: PresentImage() dispose surfaces 14/06/2006 10:21:44 AM StreamBufferPlayer9: Cleanup done 14/06/2006 10:21:44 AM StreamBufferPlayer9:grapbuilder=null 14/06/2006 10:21:44 AM add cmd:MediaPortal.TV.Recording.TimeShiftTvCommand #1 14/06/2006 10:21:44 AM Recorder:StartTimeshift tv Nine Digital 14/06/2006 10:21:44 AM Recorder: find free card 14/06/2006 10:21:44 AM Command:Stop all card except card:1 14/06/2006 10:21:44 AM Recorder: tv channel changed:Nine Digital 14/06/2006 10:21:44 AM teletext: clear teletext cache 14/06/2006 10:21:44 AM Recorder: found free card 2 prio:1 name:DNTV Live!
