I dont know the mechanics of parent companies but I expect if a cable channel wants more money it has to make a very good case for it. Then the question becomes whether or not NBC/Universal thought Enterprise was worth it. Considering that in contrast they would have full ownership for any rebroadcast and DVD rights for BSG its no competition. So I guess we can assume the answer was 'no'.
Didnt think about the writers strike. However, since it has been many months since the last new episode (Razor not included) maybe all the new ones have had scripts ready to go for awhile now. Of course any rewrites would be tough.
BSG's production has been cut short due to the strike. They do not shoot with enough lead time to have had the entire season done. Production was scheduled to shoot through March (10 eps done so far, scheduled for 12 more). The strike is affecting every episodic on SciFi except the current season of SGA, which has been on a shelf for a while due to the way SciFi scheduled the series broadcast window alongside Sky for 06/07. The strike will most likely affect the next season of SGA, however; esp if it continues into Jan/Feb.
The way that economics work in television, there is no way SciFi would have been able to pay for Enterprise with their current strategy/budget structure (they would have been required to pony up part of the production cost in order to keep it on the air, in addition to the license fee) and make that money back in any sensible fashion. The economics of tv are based on risk and minimizing your exposure if the show fails, and it's ridiculously complex. There is no chance they would have taken on Enterprise, esp with the ratings the way they were in the final season. Keep in mind SciFi partners on everything, aside from some of the low budget original movies they air. Majority of SciFi's episodic is partnered with Sky in the UK, and things like Tin Man are partnership sponsored - very little of what SciFi airs is coming straight from their seemingly deep corporate pockets, and they rarely own programming on their own outright - they always co-own with someone else. Right now, SciFi kicks in 2/3 of SGA's ~$1.8-2m per ep budget. Although the show is owned by MGM, SciFi does have a complicated deal where they make their money back. BSG is paid for within the Uni Media Studios envelope, but it's a complex formula of money coming in from different entities under that umbrella, each with their own agenda. Last I've heard, BSG was coming in on the lower side of $1-1.5m per ep. There's some outside money also coming in, as well, from Canada and the UK. And all of this pays for HD broadcast that will hopefully make it onto Dish screens this week. (lame attempt to tie it back to the thread!)
