Picture Freeze / Crash when I turn off TV and back on

[Lindhardsen]

Hi All!

This is my first bug/error report, and I really wnat to help, so please don't kill me if it's not a perfect report!

I have a problem when I watch TV, and then turn of the physical TV (useful e.g. when you want to have MTV or VH1 as background music without having your 50" consuming power).

When I turn off the TV, everything works as I expect = Sound comes out of my speakers (connected to my reciever, not to the TV).

It's when I turn the TV back on again, that the problem occurs:
The music or "sound" is still playing, but the picture has frozen, and the MP Test tool i laying active in the background.
The funny thing here (I think), is that it is not the picture from when I turned off the TV, that is frozen. It is the picture that i on when I turn back on the TV.

For all I can see, the MediaPortel.exe is still active in task manager (and the music is playing), so I do not know if this is related to MP or my display drivers?

To get rid of the problem, I can press ALT-F4 to shut down MP.


I have been having this problem ever since I started using MP (pre 0.2.3)

Kind regards,
Jan

Hi,
I think you have had this problems since the combination of Vista & HDMI. The reason it's that graphic output it's turned off when TV it's off & turns on when you turn TV on again & MP does then not now where to render (like a game) so it's get stuck & lost.
If you could use a dual view setup it will solve it, if you can force graphic output even when HDMI it's not in use it will solve the problem(some reg hacks or whatever). I know some of the devs have tried to solve it but no success so fare.

Ok, that sounds reasonable except for 2 small issues:

1. The picture Freeze when I turn the TV back on, not when I turn it off
2. I have never experienced the same problem DVBViewer

I guess that the second point can be explained by DVBViewer using some other technology for handling the graphics?
But the first one is a bit more triggy

I can live with this, but the WAF for this is very low, so I really hope that it is possible to fix this???

Hi,
What dvbviewer use i don't know, but MP renders just like games with exclusive to directx & when graphic card output it's lost MP looses it. This is a known ATI issue, nvidia has a forced option but no solution for ATI yet.

Here from your log you can see where MP looses graphic card(if this it's when you turned off or on i dunno):

Ok, so what you are saying is basically that this is not related to MP, and there is not much that can be done about it, unless change to a Nvidia adapter?

Thanks for your feedback!

Hi,
As i said earlier some are/have been(not sure about progress) trying to work around this on MP side.
I'm sure ATI will come up with a option(like force TV on when using s-vhs out as i still do ), but when they will i dunno.

I have lots of issues with vista & ATI(nvidia too) when it comes to different things, so it's not funny & most of the time MP(also games does it) triggers those since it uses DirectX & VMR/EVR renderer.

Seems like somebody else have made a bug report as well, and now it is actually targeted for correction in RC 2
