[QUOTE="tourettes, post: 649392, member: 10858"] d3dapp: Graphic adapter 'NVIDIA ION' is using driver version '8.17.12.5896' ION doesn't have enough CPU / GPU power to combine audio renderer (timestreching requires quite much CPU and ION has less than minimal CPU reserve). Audio renderer needs to drop lot of samples based on the log. Same has been seen on team's internal testing. Looks like ION's wont be able to take use of the new audio renderer (unless we manage to optimize the code more). Looks like MP itself would have had quite serious error: [code] 2010-08-17 21:33:46.859200 [Info.][MPMain(1)]: Exception :System.NullReferenceException: Object reference not set to an instance of an object. at MediaPortal.Player.BaseTSReaderPlayer.Process() at MediaPortal.Player.g_Player.Process() at MediaPortalApp.OnProcess() at MediaPortal.D3DApp.Application_Idle(Object sender, EventArgs e) at System.Windows.Forms.Application.ThreadContext.System.Windows.Forms.UnsafeNativeMethods.IMsoComponent.FDoIdle(Int32 grfidlef) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at MediaPortalApp.Main(String[] args) [/code] This would probably stop the rendering loop completely and seems as a hang to user.
