The oldest ebuild uses SRC_URI="http://powarman.dyndns.org/hgwebdir.cgi/v4l-dvb-saa716x/archive/${HG_REVISION}.tar.gz but the server can not be found any more.
This is true, I intended to remove media-tv/v4l-dvb-saa716x-0.0.1_p20140322 when the most recent version is stabilized - see Bug 624692 Anyway, thx for reporting that.
