[mythtv-users] Do I need a new DVI cable for 1080p?

I have a new 37" Westinghouse panel that offers 1080p through DVI. I
have it hooked up to my Pentium 4 3.0GHz MythTV frontend/backend and
its Nvidia 6200TC card with the DVI-D cable that came with my
four-year old 17" monitor.
The picture looks fantastic, but having never owned a HDTV before I don't
know if I'm missing out on something. Two things:
1) When there's movement of the entire picture (if, say, the camera
pans or zooms, as opposed to a person walking across a static room)
when playing a HD recording, sometimes I'll see the top 1/6 of the
screen slightly out of phrase with the remainder; it changes
slightly ahead or behind the rest. Otherwise, the picture is
entirely consistent. Is this simply a function of the computer not
being able to quite keep up with the work of displaying the
movement? I do have Myth deinterlacing with the kernel codec
without XvMC, have OpenGL XV sync on on both nvidia-settings and
Myth, and am using Jarod Wilson's modeline for this specific panel.
2) /var/log/Xorg.log tells me that the card has a single link
connection to the display. Should I buy a new, explicitly dual-link
DVI cable? My cable's connectors have all the pins needed for dual
link, but I don't know if that's the only factor involved in
whether a cable is dual-link compliant or not.
