I have no idea what this feature of the SAA7146 is supposed to have to
do with simultaneous recording and playback of MPEG2 streams.
Or what are you trying to do? 
The dual ported RAM through which the communication with the AV7110 is
performed is connected to the DEBI port of the SAA7146. The YCrCb 
output of the AV7110 is connected to one of the grahics ports of the SAA7146.
