I might as well just add to this post: I am trying to connect a LaserDisc player to my Happague 2250 and it isn't working. I have plugged in the yellow RCA cable(composite video) and have searched for channels with WinTV and it shows channel 73 as being the composite video channel but when I tune to 73 it just shows a blue screen, no video. I would really love to get this think working, there is no reason why it shouldn't be.
