OK. 50 plugins doesn't sound impossible to deal with. But they have to be in one place, as Manuel mentioned.
Name these 50 unmaintained plugins and then we can check when and how they'll be moved to vdr-developer.org.
there is a small list, ~30 plugins on https://bugs.gentoo.org/show_bug.cgi?id=414177 and his depended bugs. they fails early on the obsolet i18n handling
beware, this list is not complet, iam fixed a lot of plugins in the background, most on user pressure ;)
Anyway, i think the plugins will kicked if vdr-2.0 goes in the maintree, while there is no feedback/request from the users
