Joe, Yeah, the explanation of ground looping that I gave came straight from Newtek; i.e. there should only be ONE connection between the chassis of the Toaster and any single piece of equipment, ostensibly that one connection being the ground provided by a video cable connecting the two. Of course, to follow this through completely, we're talking about also ensuring that there is no ground connection between that deck and any other deck connected to the Toaster. This will involve some inconvenience for me, but I'm gonna try it anyway. My "B" source deck, a UVW-1600 normally feeds a component signal into the UVW-1800's component input. When I'm doing straight cuts, I just flip the input switch on the 1800 to 'Component' for a cleaner signal. Of course, those three BNC cables are providing 3 ground connections between those 2 decks; then both decks are grounded to the Toaster via a BNC cable each, which definitely constitutes a ground loop according to Newtek, AND, all of that doesn't even take my nice network of interconnecting ground wires into account… Then there's also the consideration of audio cabling: my Amiga feeds its audio outputs into a little Fostex sub-mixer, which then feeds into the main mixing board, which of course also receives feeds from every other piece of audio-producing gear in the suite, including the aformentioned video decks. This just keeps going and going and going… OTOH, my problem tends to look better the longer the gear is on; according to Newtek, this suggests that the problem is NOT a ground loop, but possibly an interaction between the Toaster and something else. This afternoon, I'm checking the possibility of it being an interaction between the Toaster and my DPS TBC IV's. Glenn Scott pointed out to me a section in the DPS TBC IV manual called "Adjusting the Toaster", that describes problems that can occur if the two are not properly adjusted to work together; oddly enough, I've missed this paragraph all this time, and the possible symptoms listed in the manual are absolutely identical to mine in every respect. I'll know in a few hours… Jerry
