Hi Bob,
I’m having similar problem with newly purchase mini converter by blackmagicdesign (analog to sdi) when I tried to connect the component (three colors) from the output of Blu-ray player, it was recognized by Anycast Station (HD-SDI input)meaning i’m getting nice picture (the video output in Anycast Station was set to HD 16:9). When I try to use the regular DVD player with component (turning off the progressive scan) signal would not come out from the anycast. I tried to use the composite and switching the #5 switch to on position, still no signal (I tried to change the video output signal to Anycast to 4:3 still no signal). I bought the item brand new. thanks for your help Bob and anybody that could help is welcome.
