Expected frame rate

Hi all!

What frame rate (fps) should be expected from an 8-chip bt878 16-input card? Each chip is capable of 30fps, the card total is 240fps. If I setup a monitor using /dev/video0 - channel 0 I am able to get 30fps, but the instant I setup a monitor using /dev/video0 - channel 1, the rate on both monitors drops to 5fps. I expected to get something lower than 15fps (30fps/2channels) from each channel from the same device... but 5 seems way too low. 10fps would be great for me... Is there any way to get a higher frame rate?

Here's something else: If I delete the monitor on channel 1, I keep on getting 5fps on channel 0 until I restart ZM.

The card is bluecherry's PV183-16.

Regards,

Gonzalo
