pbiggs:I doubt that you've been on the internet since it started, </pedant>
You believe what you like - I was on BT internet on dial up in early 90's which is round about when the 1st ISP's started to make access available in the uk.
Also, no offence but acting as an advert for BT Vision does nothing to help the OP solve his problem.
@ Bartlett, I don't know if connection problems are the cause of your failed recordings but it sounds possible to me.
Unfortunately, if it is, I have little hope for you in getting a solution. I had around 5 or 6 years of nothing but trouble with my broadband and BT wouldn't even send me an engineer (to the best of my memory). It was so bad I left and went to Talk Talk. I still had problems there but after 2 years finally got some serious help and 3 engineers (although each one was a struggle to get). They found multiple problems at the exchange and on the line. I now have a much better line, but it still slows and pauses occasionally when the SNR ratio goes low although it rarely drops completely now.
However, the chances of me ever recording anything without interruption are I think remote and considering I don't actually know anyone with a 100% reliable fast connection other than our poster above, I have to say my view of TV over the internet remains the same.
I still have BT trying to get me back as a customer - no chance!!! My phone / broadband costs on average £20-23 per month all in now compared to £60 per month with BT and I have a better line!
(all phone calls except 0845's and mobiles, both domestic and international are free 24/7)
As for TV, I've bought HD Freesat. A far more reliable option I think.
