hi all, does anyone own a dhd4000 and a matsui 2121 video/ir sender, wondering if the IR sender worked with the remote for the dhd4000. matsui 2121: av transmit freq. 2.4GHz Remote control freq. 433.92GHz it doesnt work with my old nokia 9850t remote control it was not in the supported IR range. is this because the nokia wasnt standard or are a lot of devices going to be the same?
