Hi, I have some problem running zoneminder with two 8 channel PCI CCTV capture card based on bt878 chip. Both card have eight bt878a chipset.
When use zoneminder with both card I have bad picture, some extra line. see picture

When I use only one card evrything is all right.

My system is Debian lenny/sid, kernel 2.6.26-1-686-bigmem, CPU Pentium D 3.40GHz 1,5GB RAM

I get that if I try and up the display size to something the card dont like, try reducing the picture size and see if it clears..

Try reducing your fps. I have two 4 port cards with 6 cameras and use maximum FPS 10 and Alarm FPS 18 and it works great. Also check to make sure under the source tab you have the correct Device Format. I have NTSC.

This happen on all resolution eg 320x240, 352x288 and higher. Only if I remove one of this card evrything is working fine :/

I have correct settings of cameras becouse when I use one card on this same setting and all 8 cameras is working fine.
I will try to reduce FPS, but my card support 200fps (this is 25fps per camera)

Reducing fps is no take effect, still I have this lines.

Blink, I have this same issue and this is the fix:

Not enabled inputs without a camera attached to them. So, if you have only 5 cameras, disable the rest of cards inputs (set to NONE each input, and uncheck the enable checkbox)

Tell me what happens now.

Try restarting Zoneminder whenever you change a monitor Device Path or Device Channel setting.

Did Normando's suggestion work? I'm not currently having this issue but I hate going through threads where fixes are never confirmed.

When I back to home I try this solution.

---- EDIT -----

I must confirm, when You use two card You must disable nonconected inputs. Today I will tested all 12 camera and make 4 slots empty
