I had a written explanation of the whole circuit that took me more than an hour but I lost it due to switching browser planes    . The upshot of the story is that I agree with you to remove the ICs and transistors in the circuit or at least cut the printed circuit traces to disabled the BDC-dec function and get bare access to the LB1641 motordriver IC. I looked at some other information of a Sony TAF319R unit. There they use the same processor M50761-291P, but it has a complete different function, different firmware. The device IC201 might be a SIRCS decoder with NEC protocol firmware?
