Hi Peter,
Glad it's working out well for you. Of course this is only representative of what would have been possible in the early days. With the converter we are feeding a digitally generated signal directly to the Televisor. Originally we would have had to contend with such things as signal fade, bandwidth limitations, and so on.
I agree with Jeff that the DC coupled output from the converter is most likely what's making the output more stable than that from an audio source. Most audio sources are AC coupled, so the black level, and even the sync pulses will change depending on the scene. This is why you may have lost sync on scene changes before.
All this means the image with the converter is as good as you could have obtained under ideal conditions back in the 20's and 30's, and it certainly makes for an enjoyable watching experience today!
