Moth3r: I see in my Device Manager that I have two entries for my PDI Deluxe card (both with exactly the same wording). Digging into the "Details" of each of those two, going through the list ("Device Instance ID" "Matching Device ID", etc), I find that a what they say in the big white field does not always match from one to the other. (One's sting of stuff will end in "48" and that other in "49", things like that.) But I notice that in "General/Location" or their two properties pages, one entry reads "PCI bus 0, device 9, function 0" and the other reads "PCI bus 0, device 9, function 1". Is this just a complicated device that needs two Device Manager entries, or does this point to me having screwed up on installing the driver(s) somehow? This is particular area (deciphering device driver details) is not my area of expertise at all I freely admit. Is there a better place to look for that setting ("frames or fields") than here in the device manager?

And 29.970. Cool to finally have that setting nailed!

Arnie: (Putting very briefly) With NTSC, only some of the frames are interlaced, the others look progressive. So IVTC for NTSC does both some de-interlacing and frame dropping (plus the frame rate change) in the correct patterns.

The footage I will be transferring down the road (after I have adequate knowledge and experience) is indeed from sources that I will want to keep interlaced: Camcorder stuff, super-8 films footage transferred in ways that did not assure 24fps accuracy, would not be good candidates for doing ITVC. Hence, I wish to just leave most if not all of it interlaced. For my tests right now, I'm obviously not using (wearing out) those tapes; just more disposable stuff.
