As Guy states,I don't think this will work without a tv?
I'm pretty sure that there is no ir receiver within the DVD-1.The control data is generated either in the tv or via link component.
I did manage to control a VHS82 vcr via the tape 2 port of the BM5000 years ago,to use the vcr as an audio recorder,but I think that we had to make an interface module to adapt the data pulses.
It did work very well,and the underrated hi-fi sound facilty of the vcr produced great recording quality of some of the Millenium concerts at 2000.
Another way would be to use an MCL receiver,again via an interface,connected directly to the Scart socket of the machine.
Not an off the shelf solution,but other's may have more idea's?
