I signed up to BT Vision in April this year, after being offered a deal as a longstanding BT customer. However I'm very disappointed.
The programme takes at least three minutes to load every time you switch the TV on - it's like going back to the 1970s waiting for a TV to warm up.
And it has when recording two half hour programmes on the run recorded 3 x 20 minute bursts instead and sometimes lost sound altogether (curiously always on ITV).
On catch-up TV only BBC is free, ITV and C4 you have to pay for.
The saleswoman who signed me up also neglected to set up the direct debit which meant I got stung for a bill of £60 (the processing fee was later refunded by BT after I complained).
All in all it has not been a pleasant experience.
BT refuses to cancel my 12 month contract on the grounds that a) the saleswoman did not mention catch-up TV in the call and b) I can get some service on BT Vision therefore it can't be cancelled on the grounds I get no service at all.
I'm sure they are absolutely correct that I cannot cancel BT Vision under the wording of my contract. But given the difficulties I've had with the service, the frustrations of getting it to work and failing, I'm afraid that I can't recommend it to anyone else.
