Another thing to consider is there are never 14 games going at the same time, maybe eight tops, you may want to reduce the number of sat boxes you install. It's going to be tough to insert fourteen channels into the cable system, you will need a few channels between each modulated channel to avoid interference so you'll have to trap out a good chunk of the higher cable channels to get the head room, hoping you don't eliminate a channel the bar needs to show. If you want the HDTVs to actually show HD you'll have to wire component video from the HD-20s directly to the sets. You stated you had 14 HD-20s and 35 TVs, don't know if all the TVs are HD, if they are you will need a component video spitter or "switch" to connected HD signal to all the sets. Also watch out for the delay issue between analog and digital broadcasts (if a TV is on basic cable FOX and another is on sat HD FOX there will be a delay) I've done alot of sports bars and there is tons of things to consider when designing the system, ease of use being one of the most important. When you start modulating alot of channels and doubling up TVs on the same sat boxes operation is going to become a nightmare, it has to easy enough for the employees to use. Make sure you and the owner are on the same page on what he wants and what it will take to control it.
