Bad monkey!

Channel SNR irrelevant, however that cable modem's return SNR must be above 18 to receive a reasonable service, that's the minimum for a grief free service. As it drops below this service gets progressively worse.

To OP the question about TV reception is VERY relevant because if the downstream signal from ntl isn't good enough for cable modem you'll see artifacts on your digital TV reception dude.

Downstream received signal power = 8.8 dBmV
Yipes, got a 6db forward path conditioner you could pop on that, that's running pretty hot!
