Post a log file from the frontend from startup through playing a file and doing the glitching skip / ff then exit.
</p>
<p style="margin: 0 0 1em 0; color: black;">I assume that both BE are fixes/0.28? And that you are using the same mythfrontend install on the FE and just changing the config.xml file to swap which BE pointing to?<br>
