I copy the existing mythtv ebuild and feed it new SVN source. Like this:
  mkdir svn-src
  cd svn-src
  svn co https://blahblahblah
  cd ..
  mv svn-src/mythtv mythtv-0.19
  tar -cjf mythtv-0.19-rXXXX.tar.bz2 mythtv-0.19

Then copy your existing 0.19 ebuild to 
/usr/local/portage/media-tv/mythtv/mythtv-0.19-r119.ebuild
(the 119 is just a version number I use internally. Call it whatever you 
want. Make sure you have your
portage overlay setup first):
  cp /usr/portage/media-tv/mythtv/mythtv-0.19-r1.ebuild 
/usr/local/portage/media-tv/mythtv/mythtv-0.19-r119.ebuild

Modify the new ebuild to use your new tar.bz2, instead of the original 
tar.bz2.
Comment out any epatch lines.
  vim /usr/local/portage/media-tv/mythtv/mythtv-0.19-r119.ebuild

Rebuild the digest:
  ebuild /usr/local/portage/media-tv/mythtv/mythtv-0.19-r119.ebuild digest

Emerge the new SVN version:
  emerge =media-tv/mythtv-0.19-r119

The advantage is that your filesystem stays clean and you can build 
binary packages if you have
a couple of Gentoo machines like I do. The disadvantage is that the 
process takes a while, and
you can't readily hack the code like you can when you build directly 
from SVN without portage.
So I use this method for "production" Gentoo mythtv machines, and use 
SVN directly for my
devel box.
