I've only used BSTV a couple of times, so I can't speak to all of the issues, but, I will try to shed some light on a few things...
The athletic department shelled out quite a bit of money to put a three-camera operation into place, including switching equipment. This was a major upgrade from just using the standard video camera that was used for recording games.
However, much of the problem has been a lack of performance from Broadcast International. I know that on game nights at B-H, there have been a ton of phone calls placed from one person to their support staff, because of problems. I don't know all of the tech issues, but some have been as simple as bad website scripting on the part of BI. Of course, Montana fans crashed the system a number of times during the football season, because BI wasn't prepared for the server demands.
