[mythtv-users] How to use SVN for most recent improvements

[scott at tbwifi.ca]

I have downloads the 20a plugins and have a couple issues with MythArchive
that sound like they may have been fixed in an upgraded SVN.  Take note
that I am very green and have not used a system related to SVN and I don't
know how to use it.  Can someone please give me a basic howto on getting
the latest inprovements since the release of mythtv 0.20a and myth-plugins
0.20a?

Thank you,
Scott
