MP1 initial difficulties (3 Viewers)

After a reinstallation of MP1 1.39 x86, I have the problem that a disc is always requested after the start. This cannot be clicked away either.

After a reinstallation of MP1 1.39 x86, I have the problem that a disc is always requested after the start.

I don't think that I can help with this error (the log entries don't mean anything to me), but your "Error.1" log file shows an error with the DWHD skin:

[2026-10-17 19:53:45,037] [Error  ] [MPMain   ] [ERROR] - GUIWindow:OnWindowLoaded 'C:\ProgramData\Team MediaPortal\MediaPortal\Skin\DefaultWideHD\videoOverlay.xml' control id:0 ex:Das Objekt mit dem Typ "MediaPortal.GUI.Library.GUIGroup" kann nicht in den Typ "MediaPortal.GUI.Library.GUIImage" konvertiert werden.    bei System.RuntimeType.TryChangeType(Object value, Binder binder, CultureInfo culture, Boolean needsSpecialCast)

I think that @catavolt or @High_Five need to look at it. (It may or may not be relevant to the DVD error.)

It can't be a skin problem, since I have the same issue with PureVision.

I have just tried to reproduce your problem on my default laptop (64-bit MP 1.39.0 on 64-bit Windows 10). My laptop does not have an integral CD/DVD drive, so I plugged in a USB CD/DVD drive.

I encounter the same DWHD error as you did (for "Music" as well as "Video", so possibly present on other panels too), but I have not been able to trigger the "Please load a DVD" error.

I have virtually no plugins installed, whereas I notice that you have many plugins installed. It would be worth trying your testcase with most plugins disabled, just to see if it is one of those that is causing the problem. If I remember correctly, when you run MP via the "MP Watchdog" tool, it does disable (temporarily) all optional plugins, so that would avoid having to disable all optional plugins manually.

Remember to enable DEBUG logging before running the Watchdog (I don't know whether the Watchdog will do this for you).

Same result with watchdog

I was able to narrow down the problem. If the GUI-config 'HomeScreen prefer Classic' is clicked on the error. Not at 'HomeScreen prefer Basic'. Maybe that helps.

From your logs, I notice that the DVD error also occurs with the "Titan" skin. Unfortunately, it does not occur on my system.

The "Classic Home" panel has a list of selections, with the top selection being "Play DVD". This is the selection that has the focus when the panel is displayed. The effect that you are seeing is equivalent to some part of the system pressing the OK button or ENTER key whenever the panel is displayed.

There are also multiple occurrences of this error:

HideVolumeOSD: Multiple pairs found!​

These errors precede the DVD error, so it may be these that are triggering the DVD error. Unfortunately, I don't know what this error message means.

It is rare that I can provide a solution, but I do try to provide a workaround. If the error occurs only for "Classic Home", then the workaround is to use "Basic Home". It will need one of the developers to investigate this further.

This error occurs when attempting to open the DVD plugin. According to the log, when MP starts up, it tries to open the plugin but is unable to do so because there is no disc, so it returns to the initial screen.

I don't know why that happens.

HideVolumeOSD: Multiple pairs found!

It's possible that something has changed in Windows, and MP is finding more than one Volume OSD window.

There are also multiple occurrences of this error:
HideVolumeOSD: Multiple pairs found.
These errors precede the DVD error, so it may be these that are triggering the DVD error.

@harryzwo : Since the volume error occurs before the DVD error, it makes sense to try to fix the volume error first, just in case it is that error that is causing the DVD error.

Do you have an unusual setup for the audio from the HTPC? There are these ways of getting audio from the HTPC:

• HDMI audio carried in the HDMI cable connecting your HTPC to the TV.
• HDMI audio from the HTPC to a home-theatre audio amplifier, with the TV signals then being forwarded to the TV.
• USB audio from the HTPC to the USB audio input of a DAC or digital amplifier (this is what I use).
• Analogue audio from the HTPC to an analogue audio amplifier.

Which are you using?

The error message possibly suggests that you have more than one audio output method active, but this is just a guess.

CyberSimian's suggestion to fix the volume error first sounds sensible, since the HideVolumeOSD pairs appear ahead of the GUIDisc init in the log. The SelectDVDHandler line showing ShowSelectDVDDialog right after GUIHome reinitialises does fit the idea that an ENTER or OK is being fired automatically. On the audio question, the setup details would settle whether two outputs are active at once. If Classic Home is the only affected panel, running Basic Home as a temporary workaround until a developer looks at the OSD lookup seems reasonable.
