I'm getting a similar result..actually it's alot worse for me,when i do a route trace from the dos command;of the first seven servers associated with NTL i get alot of packet loss until i leave the NTL servers(i have had upto a 38% packet loss most of the time all lost on NTL servers)

.
I am migrating to BT on th 8/2/5 because i've heard alot about NTL b/b being crap.I will post the performance of BT.By the way i use my NTL B/B 1.5m for xbox gaming so packet loss is unbelievably vital.......bye.
