Works great! I tested all recordings which did not play with the old 
firmware. No problems with teletext re-insertion and OSD until now.

BTW, is it feasible to extend this concept in the future? 
If video output is disabled, the B-frame/reference-frame buffers in 
SDRAM could be used for a full-sized, full-color OSD.
Might be interesting for future applications...
