The way the last engineer explained it to me was that NTL are trying to push too much down too little a pipe so these problems keep happening.
Yeah well I didn't believe him either.
I am seriously considering the freeview box and and ditching everything but the BB and phone from NTL.Frankly counting up the programmes I really must watch as opposed to those I don't I'm wasting my money.This way I can afford to upgrade the BB as well.
However this does not help you and I'm afraid that there appears to be no 'fix' ever planned either,as of course this is not a paid for service as NTL love to point out but a freebie.
