Mythbackend does understand RTSP/RTP protocol, at least somewhat.  I
think one of the network tuners uses it (Ceton?).  So I have taken
advantage of that to get it to record using SAT>IP URLs from

So before you think of using an external recorder, try setting up a
channel for IPTV and using the RTSP URLs for your HDMI encoder and see
if it works.  See this page for how to create an IPTV source and
