Hi,

I have a DVR card, 4x Conexant chip 878 and 100FPS.
The problem is that when I run 16 channels is the speed is 2.21 fps per channel.
When I run 8 channels a speed is 4fps per channal.
With 4 channels, I get the speed of 20fps per channel.
Why when I run 8 channels are not getting the speed 12.5 fps per channel?

Modprobe:

alias char-major-81 videodev
options i2c-algo-bit bit_test = 1
options bttv card = 133,132,133,133

Zoneminder 8xcam:

1: / dev/video0 (0)
2: / dev/video0 (1)
3: / dev/video1 (4)
4: / dev/video1 (5)
5: / dev/video2 (8 )
6: / dev/video2 (9)
7: / dev/video3 (12)
8: / dev/video3 (13)

That's about right. On a fast system, a 4 split chip will get 3-5fps depending on load because of video switching and loss of frames.
