send anything other than itself.<br>

For any mythtv setup that uses more than a single machine that is both back and front end, you<br>
/must/ give every device an IP address and supply that address to mythtv through setup. That is the<br>
only way that the backend knows where everything is.<br>

Meh. I meant "If the frontend supplies that address to the backend, the backend won't know where to send anything other than itself."</blockquote><div><br></div><div>Thanks.

The IP addresses in mythtv-setup/General are already set to 192.168.1.100. So I think it's a field I need to change in the database (hostname?), but I don't know how to do that yet - looking into it now. But that doesn't sound completely right either, since this database is a copy of the database on my old machine (with the same 192.168.1.100 IP address) where mythweb and mythtv-status worked fine.</div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">Am I on the right track?</div></div></div></div>
