Signal is too high for d3. Your uncorrectable codewords count looks as if either you have a tap issue (since your tv is acting badly) or your modem outlet is ran through your house amp. D3 needs to be as close to 0db as possible downstream and your upstream looks ok but the snr which you cant see is what can break your latency.
Huh? Picking the worst numbers for each channel:
8.5dBmV is pretty well within spec. -10 to +10 is conservative, DOCSIS spec is -15 to +15. 39.9dB is great for SNR. 48.2 is a nice number of the upload level to be at. 40-52 is within spec. If his modem has been up for any length of time, 28 correctable and 117 uncorrectables is practically nothing.
His lag problems are likely elsewhere.

is there anything you'd suggest checking? or how i could troubleshoot this problem i have a tech coming over on the 11th and he/she will be the 14th in 4 months i want to be fully prepared and get them working on what needs to be done to fix it... or point me in the right direction so i can fix it myself.

also on the dhcp missing bp configuration received response errors are all from my modems mac to a mac i dont know and can't find what it belongs to... hope this helps!
