I have 10 HD cameras and have used BI over 6 years. Everything worked great. Recently however the recordings shown on the clips list won't play. Or at least some of them. It is weird Everything recorded after exactly 10AM will play fine. Yesterday I went in and uninstalled all extra programs on my computer especially any dealing with the video card. Then I cleaned out trash and scanned and repaired registry, but still no luck. Right now I am going to scan disk for errors but the 10AM thing makes me thin it is somthing else. I have also used the clean and repair database option, which deletes the clip titles of the clips that won't play.
