FYI, a follow up to my RFI hunting adventure: I ordered a bunch of ferrite cores from Mouser, Part #623-0431176451, at about $7.00 each. They have a 0.72 inch inner diameter.
The offending HDMI cables are fairly thick; I could only manage two complete turns and still be able to snap the core shut. Three turns and I had to zip-tie the core shut. The cores helped immensely. I achieved the best results with one core with three turns and a second core added to the cable with two turns, both on the DVR end of the cable. The RFI has been abated about 95%. Question: does the tightest of the coils going through the core have any affect on the impedance? Thanks for everyone's help on this issue!!
