Wayne: The component inputs on a D2 machine are not the same as Beta/MII inputs (naturally! That would make sense! :-> If anything's to be called D2 inputs, I'd suppose they'd be it, though I understand very few users use them. I don't understand the relationship between D2 tape format and the internal "D2" signal processing the Toaster uses. Only that they are both 4:2:2, which, adding to the confusion, is sometimnes referred to as "component digital". The historical advantage to D2 (and it's major selling point) is that whatever signal you input to a D2 VTR, you'l get the exact signal out again, generation after generation. In the real world however, there is some signal loss after about 30-40 generations. Of course, no edit should require 40 passes. The other advantage to D2 is the error-c correction circuitry-basically fancy dropout compensators. This is superb and will fix many problems, although the same problems are usually generated by the D2 transport itself. I'll try to get some specific info regarding the D2 recording system. My roomate is a tech at the local TV station. BTW, last time I checked, a Sony D2 editor was running about $80,000. Trent/ReAnimators
