Montage comes up showing the same camera twice.

When montage is clicked most of the time I see the same camera twice. If I reload about 10 times I get the correct view of both of my cameras. This happens in both chrome and firefox.
I am running centos 5.3 with 2 pci cards from Hong Hong with conexant chip sets.
I have 2 monitors setup.
Monitor 1 /dev/video0 Channel 0
Monitor 2 /dev/video1 Channel 0
I was wondering if anyone knew how to resolve this.

Do you have unchecked V4L_MULTI_BUFFER on Options -> Config???
Similar issue here

We've got four IP cameras, but see the same issue here. The V4L_Multi_Buffer setting is checked. If we reload enough times we might get the all four cameras, but most of the time we get at least one repeat and one camera missing. Sometimes we'll get four of the same camera. It's very strange.

I had this issue as well when I was running with the V4L_MULTI_BUFFER on. Out of 16 cameras it seemed to only effect a couple of them, but it was consistent. I unchecked that and all was solved for the last few months.

Changing the setting didn't help. Still getting the same effect after restarting.

V4L is not for IP cams... only for 1chipSeveralInputs...

Checked or unchecked we're still having an issue with Montage. Any ideas?

I have just installed 1.24 (following the CentOS 5 guide in the Wiki) and I also have this problem. I have four cameras, but in montage I receive 4 images of 1 camera. Reloading will change the camera displayed x4, but I never get 4 distinct images. I have unchecked V4L_MULTI_BUFFER as advised to no effect.

I'm having the same problem since I upgraded to 1.24 - it was working fine under 1.23 and now I get the same image from two different cameras intermittently or a camera will flash from blank to an image and back again each frame.
I have 3 cameras connected to a 4 input BT878 PCI card. If I disable one of the cameras it works fine (doesn't matter which one). So, it works okay with any 2 out of the 3 cameras but as soon as I enable the 3rd I get this problem.
As I said, it was working perfectly under 1.23.
I disabled the V4L_MULTI_BUFFER option but it made no difference. I finally found a workaround by increasing the number of CAPTURES_PER_FRAME to 2 as suggested in http://www.zoneminder.com/wiki/index.php/Pico2000
but unfortunately this halves the frame rate.
I would be nice to have a fix for this as a number of people seem to be having this problem with 1.24.
