I have tried playback with "deinterlace during playback" on and off, it
makes no difference. Old recordings look fine either way, new recordings
look like venetian blinds.

I have not been able to find where this is set.

No, not yet. I plan to get digital cable eventually, but from what I've
read on this list, I shouldn't have bothered with a capture card because
it seems like firewire is the only thing that works with a digital cable
box.

I have never figured out whether I should be using RTjpeg or MPEG-4 as a
codec. Under RTjpeg, there are no options at all that have anything to
do with interlacing (that I can find). Under MPEG-4, there are "Enable
Interlaced DCT encoding" and "Enable interlaced motion est". Neither is
checked.

No, not yet. I just got this card because eventually I want to go to
digital cable or satellite with HDTV, and at the time I bought it, I
thought I might not be able to get one at all unless I got it before
July 1, so yes, I have an HDTV capture card, but I don't have anything
with HDTV signals hooked to it yet, just plain old analog cable.
