MediaPortal makes it easy for you: http://wiki.team-mediaportal.com/1_MEDIAPORTAL_1/16_Support/3_Forums/2_Log_FilesI have some real weirdness. Updating to the new version went just fine with the extension installer. I installed MPExtended aswell, so didn't need to do it through the extension installer, but hey.. no worries
But when i wanted to watch live tv my screen stayed black.
At first i thought it was my update of LAV filters (updated those to 0.54), but downgrading them didn't help. Setting the codecs to MS-DTV didn't help either. So started to uninstall the other updated packages.
Last package was WifiRemote. When i did the deinstall my live tv worked again. So i reinstalled it and it turned black again. Deinstall and it works.
I could send some logs but i honestly don't know which ones i have to send.
