I've finally gotten MP to produce a log file (UAC was causing issues, if anyone out there is having MP issues under Vista, first try disabling UAC). When I go to My TV, the screen temporarily goes black, then my desktop appears (MP is still running, it's just "invisible"). I looked at the error log and I see:

2007-02-25 18:47:40.301488 [ERROR][MPMain]: Planescene(0,0,0,0,0,True,3):Unhandled exception in Error in the application. Microsoft.DirectX.Direct3D at Microsoft.DirectX.Direct3D.Device.Clear(ClearFlags flags, Int32 color, Single zdepth, Int32 stencil, Rectangle[] regions)
at Microsoft.DirectX.Direct3D.Device.Clear(ClearFlags flags, Color color, Single zdepth, Int32 stencil)
at MediaPortal.Player.PlaneScene.InternalPresentImage(Int32 width, Int32 height, Int32 arWidth, Int32 arHeight, Boolean isRepaint)

The error repeats about 20x a second. It continues untiol I exit My TV. Also, at the top of the error log is (don't know if it is related):
2007-02-25 18:47:32.582255 [ERROR][5]: SinkGraphEx.SetupTeletext(): Failed to find WST Codec
2007-02-25 18:47:33.861470 [ERROR][5]: SinkGraphEx.SetupTeletext(): Failed to find WST Codec

Anyone seen this issue/know what to do?

Line 689 of PlaneScene.cs seems to be where the problem occurs:
GUIGraphicsContext.DX9Device.Clear(ClearFlags.Target, Color.Black, 1.0f, 0);

Any suggestions?

I guess it throws an InvalidCallException. I really hope this can be fixed, it occurs every time I switch to My TV (and the TV is on).

From what I'm reading the gfx card may play a role, my card is a MSI NX7800GTX-VT2D256E

Thanks.
