Strange vertical waves on DVD playback...HALP!

I have an Oppo DVD player, rated one of the best around. Yet, when i
play DVD's, no matter what the DVD, there are these sorta-fast moving
vertical waves/bars that move from the left of the screen to the right.
They are sort of like waves of light. They're subtle, but certainly
noticeable when you're using the DVD player. They are more noticeable
in dark scenes, but if you look closely, you can see them in any scene.
Even when the DVD player is in "stop mode" and NOTHING is playing, i
can see it on the plain black screen, and on the DVD player's screen
saver.

To fix it, i have tried turning off all other equipment, switching from
interlaced to progressive scan on the TV, changing from 540p to 720p to
1080i on the DVD player, moving speakers around. All had zero effect.

I DON"T see them when i'm using my DVR, VCR, cable box, or anything
else. Only when i use the DVD player. I have not noticed this on
previous DVD players. Anyone know about this phenomenom, and how to
fix it?

I own:
Oppo OPDV971H DVD player
HDMI connection to my Sony Vega KV-34HS510 television (CRT)

Any help would be greatly appreciated.

Paul

Oppo Digital is noted for the accessibility and helpfulness of their tech
support. What did they say about this?

Yes, actually, they are very good like that... their response to me
(via email) said that it is either video calibration, interference,
ground loop or bad cable.

I recalibrated the video. Nothin'.
I moved things around, unplugged, etc to get rid of interference.
Nothin'.
Group loop? I doubt it. No other video source has this phenomenon.
Bad cable. Possible. Disconnected and re-connected cable. No
improvement.

When i re-routed the video of the Oppo player through a COMPONENT
cable, instead of the HDMI, the problem was gone. Of course, the
picture wasn't as smooth, but no waves. So, based on all that, i'm
assuming it might be the cable? Or possibly the input/output of the
HDMI for the DVD player or TV? Seeing as no other video combination...
with ANY equipment, including the DVD player itself has the problem,
EXCEPT the HDMI connection, then the problem should be the cable or
connection, right? What if i buy a new cable, and the problem
persists? i don't know where to go from there.
