<br>I looked again at the <b>mythbackend.log</b> file. There seemed to be more error messages there.<br><div style="margin-left: 40px;"><br>******************************<br>** Section with errors ****<br>*****************************<br>

<br>1. Update to the latest -fixes code to see if this has been addressed.<br>2. Compile the -fixes branch with debug symbols and follow the instructions on the <a href="http://mythtv.org">mythtv.org</a> website documentation for generating a backtrace so that the developers can see what may be causing the crash<br>
<br>This is not the same issue you had before. <br><br>But, the fact that you have your database crashing and mythtv crashing leads me to wonder if you may have a bad stick of memory causing both programs to behave badly.<br>
