Fred... this may sound strange but due to the way I have my stuff setup
on my computer desk, I have DCTV sitting atop my USR HST modem. When I
digitize from my Xapshot still video camera, if the modem is powered ON
I notice more  degeneration in the digitized results than I do if
the modem is OFF. Since the DCTV is a plastic box (FCC Class B 
certified) it could be subject to spurious RF and god knows how much
an entire Amiga system puts out :-) Soooo.. if you hve an external
modem, and you have DCTV stacked on top of it... etc. etc. Other than
that, you might want to give the boys at Digital a ring and discuss it
with 'em. 


There is a certain amount of "wiggling" when you invoke the "scan"
button.  Have you messed around with the low/hi quality buttons and
the 3 scanning settings too? Also make sure if you're using a color
camera or camcorder that is NOT a still video camera, that you are
using the "camera" seletion button, not the "tape" button.  This stuff
may be obvious but DCTV's software offers the new owner an almost
overwhelming range of choices to make when digitizing.
