Monday 4th, 7pm Disney Channel - "Kim Possible: A Sitch in Time". Ok, probably not of interest to anyone except me, but it has Michael Dorn (Worf) doing the voice of Rufus 3000, so it must be good! (Rufus being Ron Stoppable's naked mole-rat, obviously.)
Tuesday 5th, 8pm Sky One - "Stargate SG-1". Season 8 begins.
Tuesday 12th, 9pm Sky One - "Stargate Atlantis". Season 1 begins, conveniently showing right after the SG-1 episode.
Saturday 16th, 10pm, Sky One - "Battlestar Galactica". The complete mini-series (3.5 hours), that remakes/reimagines/rips off the 1970s version. (I'm reserving judgement until I've seen it.)
Monday 18th, 8pm, Sky One - "Battlestar Galactica". The new ongoing series begins.
"Charmed" season 7 and "Smallville" season 4 have now started in the USA, but probably won't be shown in the UK until January. Ditto for "Joey" season 1.
