The reason I'd prefer RTP/RTSP is that

1.) HTTP is no real-time protocol
2.) HTTP-commands can only be sent once at start of connection, but RTSP
also allows to send commands during connection.

There could also be a generic RTSP-plugin for VDR, which encodes OSD
into SPU, muxes the SPU into the A/V-stream. That way it would be
possible to connect nearly every media-player to VDR. It only would have
to support MPEG-decoding, SPU-decoding and RTSP. That way there would be
OSD and VDR could be controlled by RTSP-commands.

You have to use MPEG-TS with Xine - and port may be 3000 instead of 300.
