</div>Well, at least part of it is probably something to do with the way I<br>
do the tuning. In trying to work around some issues which I thought<br>
were the fault of my code (and now appears to have been a hardware<br>
issue), I modified my tuning code to be a bit more robust, but it was<br>
at the expense of some additional (though quite small) delays. I think<br>
what is happening is that when your system is under heavy I/O load,<br>
it's magnifying these small delays. I've got some ideas for how to<br>
improve some of this, but some of it seems to be out of my hands (in<br>
the logs you sent me earlier, I can see some sizable delays before my<br>
code even begins executing). Cumulatively, the delays are probably<br>
just enough to push it to the point where livetv gives up.<br>
<br>
One thing that may help is to turn on the slow delete option (whatever<br>
it's called). I think a big reason for the delays is that things slow<br>
down considerably when the system is trying to delete a multi-gigabyte<br>
file. The slow delete option is supposed to make this much less<br>
noticeable (I think it gradually shrinks the file a little at a time<br>
until it's finally down to zero, rather than just deleting it<br>
outright). Also, I'm not sure if it would make much difference, but I<br>
also set myth so that it keeps about 20GB of disk space free.<br>

Everything is working well except live TV. I don't think it is your patch's fault. It has been suggested that my problem was fixed in more recent .24-fixes. This brings me back to trying to get you patch applied to the latest Mythbuntu source. The repos that Mythbuntu uses to get up-to-date .24-fixes builds are:<br>
<br><a href="http://ppa.launchpad.net/mythbuntu/0.24/ubuntu" target="_blank">http://ppa.launchpad.net/mythbuntu/0.24/ubuntu</a> natty main<br><a href="http://ppa.launchpad.net/mythbuntu/testing/ubuntu" target="_blank">http://ppa.launchpad.net/mythbuntu/testing/ubuntu</a> natty main<br>
<br>I have found source code that seems correspond to my up-to-date frontend:<br><br>MythTV Version : v0.24.1-80-g1de0431<br>MythTV Branch : fixes/0.24<br>Network Protocol : 63<br>Library API : 0.24.20110505-1<br>
QT Version : 4.7.2<br><br><a href="http://ppa.launchpad.net/mythbuntu/0.24/ubuntu/pool/main/m/mythtv/mythtv_0.24.1+fixes.20110831.1de0431.orig.tar.gz" target="_blank">http://ppa.launchpad.net/mythbuntu/0.24/ubuntu/pool/main/m/mythtv/mythtv_0.24.1+fixes.20110831.1de0431.orig.tar.gz</a><br>
<br>I am not sure why the package manager knows how to pull up-to-date
.24-fixes binaries from these repos, but not source. I would expect the commands in your tutorial to pull from this location as well, but they do not. Do I need to add or modify repos in the package manager? Any ideas?<br>
