The new PlugIn-branch of VDR can already record several streams on a
transponder with low-budgets (there a also tries to do that with
full-featured DVB-S as they allow up to eight streams ...). There's also
a development of a RTP-streaming-patch. When Klaus Schmidinger claims
the development branch to be stable, the streaming-patch certainly will
be ported to plugin.
