OK. I am trying to get a 2950 myself.
I have heard good things about the LD-V4300D (some say it has a raw output and better signal than the 2950/925 however i think it's pretty old).
I have got the Service Manual of the 2950 and i think that for an electronic expert (with all the detailed diagram there is in it) its maybe easy to get the raw signal from a LD-Player
