I've watched the videos and I would say this is more a case of misunderstanding on usage. First of all, your levels are too high. You should be aiming for the 0dB level (last green) or possibly the first orange simply for visual reference.
Second, the difference between the last orange and first red is a significant level gain, and you should NOT be aiming to be "in the red." Yes, there is enough overhead to not clip the signal if the output is configured properly, but you still should not be trying to get the levels to the red. Audio engineers and experienced DJs will tell you that the best sound quality is never in the red.
