SF show transmission dates

[altariel]

I am trying to track down UK transmission dates for a couple of shows, neither of which I watched from the beginning or watched to the end. I'm poking around the net, but because I am lazy because I know what wonderful, brilliant, sparkly people you all are, perhaps there is someone who knows this kind of thing off the top of his/her head.

I need to know the start and end dates of transmission for:

Lexx
Andromeda

(Only the years, and in the UK.)

I found a website which gives terrestrial TV transmission dates, but I'm sure these first aired on Sky or Sci-Fi or whatever. Or did Lexx turn up on Channel 5 first?

Edited to say: OK, this is what net-searching has suggested so far - if anyone reading these dates thinks they're wildly wrong, please shout:

Lexx (1999-2002)
Andromeda (2000-date)

I wonder whether the peculiar format of the first Lexx season, ie it isn't really a season at all but four sort-of-film-length-episodes, affected the initial UK broadcast? But I wasn't aware of it at that point, and can't quite remember which channel showed it first anyway. Not Sky, I think.

Is it the kind of thing that would into Sci-Fi's schedule pretty well?
