last Changelog entry: Removing MythFrontend. Functionality in MythTV ebuild
Could you give a little bit more info ? I have already installed media-tv/mythtv-0.20_p11444 which is the currently latest one. The mythfrontend i used is from there. I can not seee any reference for my problem in the Changelog of the mythtv ebuilds.
Just another MythTV feature to live with. That's why everyone has scripts setup to see if MythTV is running or has crashed and restart it if it has. You can try to take it upstream and work with them over at http://svn.mythtv.org but since MythTV is so unstable it's not a Gentoo trackable thing.
I've got it running using the unstable xf86-video-mga-1.4.2 ebuild (instead of 1.4.1 stable) as xorg video driver. Hope that helps others.
