Hi John,<br><br>Im by no means an expert, but i saw the same thing when i used the mythfrontend that came with myhtbuntu 9.10, i got asked to install debug symbols, but this lead me to build mythtv from the 0.22 fixes. And that solved my problem. I dont know if that will help you, as it takes some time to make it compile if you have not done this kind of thing before<br>
<br>i followed this one, but it does not explain what other things you need apart from the mythtv source<br><br><a href="http://www.mythtv.org/docs/mythtv-HOWTO-5.html#ss5.1">http://www.mythtv.org/docs/mythtv-HOWTO-5.html#ss5.1</a><br>
<br>hope it helps you.<br>-lasse<br><br><br><br><div class="gmail_quote">On Tue, Dec 8, 2009 at 4:29 PM, John Luber <span dir="ltr"><<a href="mailto:john@luberfamily.net">john@luberfamily.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<p>Hi All,<br>
<br>
</p>
<p>I have a backend with multiple frontends all running 22924 or later
(be &
fe's). The backend has two hdhr's, a pchdtv 5500 and an SD hauppauge
150. Watching live tv on any frontend profiles results in consistently
getting "Error: Video frame
buffering failed too many times." at the top of the hour (ie; 1:00,
3:00, etc). <br>
</p>
<p>Frontends have either NVIDIA 9500GT w/ 1gb or NVIDIA 9400
w/ 1gb. Frontends use NVIDIA 195.22 but this also happens with 190
drivers as well.<br>
</p>
<p>
This problem has persisted since upgrading to .22. Did not observe this
behavior in .21 but did not watch much live tv in .21.<br>
</p>
<p>Based on observations I believe that this has something to do with
the change-over from one live tv recording file to another at the top
of the hour / change of program. I see reference in the frontend log
to the new file that should be created however I never see it in the
filesystem.<br>

<p>I've searched the tickets and found #<a href="http://svn.mythtv.org/trac/ticket/6583" target="_blank">6583</a> (reported as
closed) which sounds identical to the problem I am having and have
opened #<a href="http://svn.mythtv.org/trac/ticket/7697" target="_blank">7697</a>...<br>
</p>
<p>Anyone else having this issue? Any thoughts to a resolution or
workaround?<br>

<p>Thanks!<br>
