We've had some ideas on the VDR-ML to realize a soft-based decoding.
The simpliest idea to implement seems to be to remove the hardware-parts
from the DXR3-plugin (which encodes OSD to VOBsub), mux the A/V- and
VOBsub-stream into one stream and feed in into MPlayer in slave-mode.

This way all A/V-out-libraries of MPlayer can be used and we're no more
limited to MPEG but could replay nearly every codec.
