I recently optimized my BI system by using substreams and direct to disc recording. My cpu is now down from 60 - 70% to 25%...very nice. One odd behavior that I have noticed is when I select one of my nine cameras on the console and go to full screen, I seem to see a few moments of an previous time. Example. I double click on a camera at 10PM when its dark and I see it in full screen mode for 1/2 seconds and then It changes to the middle of the day for just a couple seconds...then goes to current live view. Not a huge deal, but never had it until I switched to using the substreams. My understanding is the when I am looking at all 9 cameras at once, I am looking at the substreams...and when I click on one of the cameras on that screen, and go full screen I'm going to the main stream. Not sure why it would revert to many many hours earlier for a few moments?
