Hello First of the Wireless 1 has known to be unstable, probably because of inteference from other electronics that use the same frequency 2,4ghz (wifi, Bluetooth, baby monitors, wireless doorbells, microwave ovens etc.) so your milage may vary. Masterlink to masterlink was not possible in the forst software revision. There is no way to check for the current software version unless you can get a dealer to check it with a servicetool. But units from serial number 19956171 should have SW 2.1 that support masterlink to masterlink. Also be sure to buy a pair that is known to work as different software revisions might not work togheter. In order for this setup to work you will have to setup the TV as a link room TV that accept audio commands. That will be V.opt 6. You will not need a separate IR receiver. Hope this is helpfull even though it might not be a optimal solution
