then run ./configure in that directory or should I make a temp copy of the
source and compile that?"<br><br></span>yes, you would have to run make in that directory since that is where the make file resides. You may make a backup of what you just downloaded with SVN for future use<span style="color: rgb(31, 73, 125);">

there a special command to simply update the changes in /usr/src/mythtv?"<br></span><br>Like Chris W. said, you would then have to 'make uninstall' the version you've installed then 'make clean' then 'configure', make and then 'make install'.
<br><br><span style="color: rgb(31, 73, 125);"></span><span style="color: rgb(31, 73, 125);"><br></span>I'm just a dumb noob myself so I make no claims but in layman terms from my understandings...<br><br>SVN is a state in which the source code is tagged with a version number, it's a living thing, patches are applied and the version numbers change so certain source code changes are associated with certain version numbers.
<br><br>To download from SVN you would issue the command at the command line: <font size="-1"><b>svn</b> co http://<b>svn</b>.<b>mythtv</b>.org/<b>svn</b>/trunk/<b>mythtv, </b></font><font size="-1"><b>svn</b> co http://<b>
svn</b>.<b>mythtv</b>.org/<b>svn</b>/trunk/<b>mythplugins, </b></font><font size="-1"><b>svn</b> co http://<b>svn</b>.<b>mythtv</b>.org/<b>svn</b>/trunk/<b>myththemes<br></b><br>This would download MythTV 'Trunk' at the latest version number or you could download a certain version number with "co -r"
e.g. </font><font size="-1"><b>svn</b> co -r 13456 http://<b>svn</b>.<b>mythtv</b>.org/<b>svn</b>/trunk/<b>mythtv</b></font><font size="-1">. <br><br>Then you configure the options using .</font>/configure after which you then run 'make' followed by 'make install'
<br><br>Once you do it a couple of times it becomes a no brainer...<br><br>AJM,<br><br>
