Um, that is what the DPX-7000 is, a device that removes CP from a video stream.
Sony's are notorious for sensitivity to CP, so be aware of that. From your description, it sounds like you have it connected properly. I don't have a manual for the device, but from the pictures, there are three adjustments that can be done.
Make sure the NTSC/PAL switch is in the correct position.
The SELECT button I would guess is to select composite or S-Video as the input/output video line. If this were set wrong, you might get the effect you are seeing.
The MODE button I have no idea about. You probably need to try it to see what works. I suspect one mode is "passthrough" which means it is not applying any changes to the video stream, which might account for it not working properly.
There are some posts about the DPX-7000 on this forum, so I recommend you do a search. The search function is your firend!
(Or at least, CAN be your friend...)
