As I don't have the abilities to do that myself, I'm looking for someone
who creates a patch for VDR to encode it's OSD to SPU-subtitle and mux
it into the A/V-output-stream sent to the DVB-driver.

When sending that A/V-stream to stdin of a programm (e.g. Mplayer)
instead of DVB-driver we could use every MPEG-capable mediaplayer as A/V
backend to VDR.

Can you code such an encoder by using parts of spuenc?
