<br />> Hello,
<br />>
<br />> I created a thread about blank screen when starting livetv which received no responses.
<br />>
<br />> In viewing other responses to other posts I saw where I can start the frontend in the command line in verbose mode. When running this command it appears that LiveTV times out because of a failure to start a recording. I don't know what this recording is or how to remove it. Can it be that this problem is due to a bad recording? Please offer your opinions.

<br />> This is the output of mythfrontend -v audio,playback:

<p><font size="2">It would be helpful to know:</font></p>
<ul>
<li><font size="2">whether this is a combined frontend/backend, or a remote frontend,</font></li>
<li><font size="2">what version you are running, </font></li>
<li><font size="2">on top of what distribution, and </font></li>
<li><font size="2">whther you compiled form source or used a package.</font></li>
</ul>
<p><font size="2">The text of the messages heps, bit it's still a little difficult to defintiely determine what the problem is. However, some clues:</font></p>
<p><font size="2">If it is a backend server with a remote frontend (rather than a combined FE/BE), you need to change the IP address in Setup to that of the remote server (or to the correct assigned name, if you're using DHCP).</font></p>
<p><font size="2">It seems really odd to me that the ringbuffer would be located in a subdirectory of /var/lib. If I recall correctly, the Live TV ringbuffer is usually in the same directory as the recordings. MythTV may not have the permissions required to write to that directory.</font></p>
