Unable to create graph (1 Viewer)

[Stéphane Lenclud]

TV just stopped working.
I was getting some error message which could have been something like:
"Unable to find program or channel"
After PC reboot I now get:
"Unable to create graph" when trying to tune on any channel.

It's a 1.9 installation. Logs attached.

Update to 1.10 pre does not fix the issue.
Fresh install of 1.10 pre does not fix the issue.

Sometimes the DD CI gets really messed up and needs to be switched off - a reboot of the PC may not be sufficient. You may want to try to switch the PC completely off and then power up again.

I just try that, did not help.
Unplug from the wall, did not help.
Uninstalled TV server. Install TV server, did not help.

Yep, HTPC_Sourcer is right.
...and if you've linked more than one CI to the tuner, you must use the patch from here:

Then try the DD-DVB Tool and test if you can watch a Sky Channel. If this works then there is an issue with MePo.

It has happened to me, albeit quite some time ago, that I could not get MePo to work anymore. Instead of searching for hours it might be easier to just delete (rename) all MePo directories, remove the MPtvdb file and install from scratch. If you have a backup of your channel list you should be up and running within 10 minutes.

Ok guys thank you so much for helping out. This community never cease to amaze me

What fix it for me was to run the DD DVBCineConfig utility.
After starting it and going into "Common Interface Module" it tells me I need to reboot cause setup as changed.
Apparently it worked out something was screwed and fixed itself.
I could tell something was amiss cause the UI was missing the usual entries.
After reboot I tried MP and I was getting the "scrambled" error instead of the "graph" error.
Went back to DVBCineConfig had to unable CAM for both my tuner as apparently all settings were reset.
One more reboot later MP TV is back online
Not sure if the many reboot before going into DVBCineConfig were needed.

Now I screwed my MP setup somewhat.
One positive point I'm now running 1.10 Pre on my production system

Yeah I have one of those, can't really upgrade MP without it
