Advertisements System: 2- PTZ cameras at diving boards, feed 2 ZVee Pro 810 digital encoders that modulate the video and send HDMI to 2 TiVo Bolt. These then feed 2 60" displays so divers can make their dive, get out of the pool and go see their dive in a delayed feed from the TiVo's. Problem: After going through the setup on the TiVo's, scanning for the modulated channel, and making this all work, about a week goes by and the TiVo will no longer pass the modulated channel. I have to force a new setup using kickstart codes and I can get them working again for another week. Info: There are NO cable cards installed on these TiVo's. Question: What can I try to get these TiVo's to stay setup. They are unusable at this time. Thank you.
