Take a look at <a href="https://code.mythtv.org/trac/ticket/12522" rel="noreferrer" target="_blank">https://code.mythtv.org/trac/ticket/12522</a><br>
If you are in a position to compile from source, you could try the patch<br>
attached to that ticket.<br>

John</blockquote></div><br></div><div class="gmail_extra">Thanks John. I will try compiling the source with the patch. I typically do a git pull every time just before I build. I do see the patch is slated for 0.27.6 release. I will do my usual pull and check to see if the patch is included. If it is not, I will patch and try. Thank you for the reply.<br></div></div>
