You know that, I know that but the scheduler doesn't. Even with 4-5
channels per card/video source the scheduler has to find the optimal
distribution of the recordings to the virtual recorders. We know that
the optimal distrubution is to record all recordings from one channel
on one virtual card. The scheduler can't take this shortcut.
