The list of available TV windows are based on media websites, TV listings and press releases. They can change based on the needs of the broadcaster or the conference.
Here's what I guessed based on the available openings (they will prove to be incorrect) and here is the current schedule for the week as several FBS games do have their time & television/webcast assignments already accounted for.
The number of six day holds available for each conference
ACC: 3 (two used: 10/6 & 10/27)
American: 1 (one used: 10/27 by ESPN)
Big 12: 3 (one used on 11/3)
Big Ten: 3 (one used: 10/27 by FOX it appears)
SEC: 1 (one used on 11/3)
Pac-12: 2 (10/6 by FOX & 11/3 by ESPN)
