I agree. Even though I've been using MythTV for year now, I've learned 
loads from formatting my 3 machines and starting from scratch with them. 
The reason for that was that my server was playing up in a couple of 
different ways (outside of Myth). I hadn't been able to get to the 
bottom of it in 6 months of on and off trying. Starting from scratch 
sorted it all out.

The 2 frontends do little more than act as frontends, so I thought that 
I'd refresh them too. When one of them wasn't working right, and the 
reason wasn't apparent, I thought I'd just wipe it and start again,

Tick.
Both frontends can access it too. I have no problems playing content.

Is this the line that was blank in the frontend? The top line in "Setup 
 > Media Settings > Video Settings > General Settings"? It was blank in 
both of my frontends. Should I make it /home/"FE-user"/Videos, even 
though that location isn't used at all?

No, I don't think there's a problem there.

Ah, maybe this is it?
The content of this file in both frontends is almost identical:

<Configuration>
<LocalHostName>my-unique-identifier-goes-here</LocalHostName>
   <Database>
     <PingHost>1</PingHost>
     <Host>192.168.0.2</Host>
     <UserName>mythtv</UserName>
     <Password>xxCorrectPasswordxx</Password>
     <DatabaseName>mythconverg</DatabaseName>
     <Port>3306</Port>
   </Database>
   <WakeOnLAN>
     <Enabled>0</Enabled>
     <SQLReconnectWaitTime>0</SQLReconnectWaitTime>
     <SQLConnectRetry>5</SQLConnectRetry>
     <Command>echo 'WOLsqlServerCommand not set'</Command>
   </WakeOnLAN>
   <UPnP>
     <UDN>
<MediaRenderer>xxxxxxxxxxxxxxxxxxxxxxxxxxxx</MediaRenderer>
     </UDN>
   </UPnP>
</Configuration>

The 'MediaRenderer' number is different on both. However, LocalHostName 
is the same in both. It just says "my-unique-identifier-goes-here".

I've never changed this before. Do I have to manually put something 
unique in here?

If so, do I then need to reconfigure something on the backend?

Thanks for helping HP-mini,
