Hi
Sorry to rock the boat but as far as I am concerned Tiscali have delivered exceptionally for me over the past 6 years from dial-up to broadband and now Tiscali talk and broadband I download huge files mainly music and video with no problems maybe you are the 1% of customers that have a problem.
2 of my friends that are using Tiscali had problems but when I went round to see them it was their settings and computer that was at fault and as soon as I corrected it they have been fine ever since. That was about 3 years ago
It isn`t always the ISP at fault mostly it is your personal settings on your pc
