Crash when switching to previous/next channel (1 Viewer)

[FlatEric]

When i switch to the previous/next tv-channel with channel down/up button MP freezes showing a frozen picture of the last channel. Switching to another channel within the tv-guide works. Using the skin default wide instead of Titan has no effect. When i select VMR9 instead of EVR as Video renderer channel-switching works, but i have stuttering video.
The logs are added in the zip-file. I cant see a problem in the logs, maybe someone can help me.

Hello

Please [always] use the watchdog (AKA debug mode) to grab log files so we get your Windows application event logs and can see the source of the crash:

Here are the complete logs of the debug mode.

For sure you have error in log

Can you describe step by step and what key did you use to Zap channel (i know that in TVHome, we can use PGUP/PGDown to zap between channel.

 

[FlatEric]

Hello,
i use eventghost to translate the remote commands to keystrokes.
For tv channel up/down i use F8 and F7 (from keyboard-shortcuts in the wiki).
Pressing PgUp/PgDown switches between the channel-groups.

 

[Sebastiii]

Ah yes PgUp/PgDown works when in TVHome but not in fullscreen
Will try F7/F8 on my side tonight.

Hello,
after upgrading to MP1.8 this issue is still a problem for me.
I hope you can see in the attached log that F7/F8 works several times but then i got a black screen.
With the Esc-key i could go back to the tv-menu so MP did not crash completely.

but then i got a black screen.

Looks like whatever key(s) you pressed caused MP to switch from ProSieben to RTL2 radio. You can expect the TV screen to be black when a radio channel is selected.

 

[FlatEric]

This is very strange, because i only pressed the channel up/down keys while watching tv.
So MP should not jump to radio-playback. Addditionally RTL2 is not part of my tv or radio channel-list.

I can only report what I see in the log files. You can read for yourself.

There is a sequence of channel changes which get quite fast.

SAT.1 is started when you enter the TV section:

Not sure what more I can say.

Addditionally RTL2 is not part of my tv or radio channel-list.

It might not be in your custom/favourite groups, but I assume it is in the "all channels" group.

My guess is that you're either not zapping within your custom/favourite group or whatever keys you're pressing are causing MP to change group.
