I am a little late in getting there...but I finally updated my TV Schedule Spreadsheet. You can find the spreadsheet via a google document right here.
There are still a few updates to make, as TV Guide isn't really helping me, leaving several 'To Be Determined' entries on their schedule grid. I filled in (and in some cases, corrected) their grid when I was researching mine.
There are a limited number of brand-new Sci-Fi shows this winter. Basically, it's a list of one - "Dollhouse". But, we do get to see the return of "Lost", "Battlestar Galactica", "Kyle XY" and "Reaper", so the TiVo is still getting a ton of use. I'd rather have better quality shows than a slew of mediocre programming anyway.
So, enjoy the spreadsheet! If you would prefer a pdf document, I created one that can be downloaded here - it just won't be updated as frequently as the spreadsheet.
