Hi there,

I have a couple of P878H-16 cards (same as http://www.zoneminder.com/forums/viewto ... 6bfcc6da95 but with up to 16 outputs per card)
Testing with one card, the four built-in ports are all working perfectly with a bttv file of "options bttv card=138,138,138,138 pll=1,1,1,1 tuner=4,4,4,4 gbuffers=16"
The card also worked with 77,77,77,77 but this caused system instability.

I am trying to get some extra cameras working on extra ports but these aren't working properly. The feeds from cameras (including those on the expansion) bleed into each other and continuously jump between each other.

I have the sources set up as /dev/video0,1,2,3 for each chip and channels 0,1,2,3 which I believe should give the full 16 ports.

The expansion boards are from ebay and for another bttv card but fit ok and do give a feed.

The server is a Dell SC440 running Ubuntu Server.

Does anyone have any idea how to fix this or should I be getting new cards?

lower you fps

when you add cameras to one on these cards you give the switching meconizem more to do and now you also get a lower fps because it can not keep up with the chip

example a 4 input 30fps can theoretically 7.5 fps per cam however in rwality you will be closer to 5 but if you try to push it to that 7.5 you will get peices from the other feeds
