I read that post and found it very disturbing. Especially the bit about BT vision because I have BTV and about the only thing that doesn't go wrong is the VoD.
If I was 'in the trade' I would not share that kind of stuff with someone that I have never met. Remember hearsay is not allowed in court for very good reasons. And yes my BT BB works very well. Slows down a bit I suspect during peak hours - probably contention but that's what I signed up for.
