This past weekend I did a restore of my LMCE installation from a system disc image previously captured using Clonezilla. Everything worked fine except that I had to set the backend IP addresses in mythtv-setup. Where 192.168.80.1 was used, I changed it to 127.0.0.1. Though the external IP had not changed, the install was broken and this fixed it in terms of allowing for viewing of live TV.
The "Don't Auto Configure" box is checked in the WebAdmin screen for the MythTV plugin.
Is this related to the restoration? Is Clonezilla a recommended way to backup and restore?
Otherwise, mythtv seems to break periodically, after weeks or days. Is this normal?
