Same camera view on all four channels

This problem has me tearing my hair out. I decided to upgrade my system from an Ubuntu amd64 8.10 server to Mythbuntu 9.10 AMD. I wanted to merge my mythtv and zoneminder servers into one box. When making an upgrade like this after so long I buy a new hard disk and perform a clean install. The install went fine but something is odd in the camera source setup. This is for zoneminder v1.24. I am using the same hardware as before, a bluecherry PV143 4 channel card. I did add the Haupauge 1600 tv tuner card for mythtv.

I can add the two cameras I had before, 1 for the front door and 1 for the side. I added the front door first and got video just fine (Channel 2). I added the side door next and at first it displayed a ghost image of the front door over the side door image. I tried several tweeks like changing to V4L version 2, moving the port the camera was connected to, with no luck. Now all cameras show the view of the first camera configured in zoneminder.

If I delete all the cameras configured, then add the side door channel first, all other cameras added show the side door view even though they point to a different channel on video0. I've googled every term I can think of to find something but with no luck. Does any body have any ideas?

I tried plugging the old hard drive system back in to see if it was a hardware thing and the hard drive died on bootup. I won't be able to access the old system.

Ok this is getting bizzare. I've experimented by adding extra monitors and I've found a weird pattern. If I have only one monitor it's able to view the approprate camera for that channel. If I add another monitor it will display the highest channel on all monitors, even though the source is pointing to different channels for each monitor.

If I have monitors on channel 0 and channel 2, it display channel 2 on all. If I have monitors on channel 0, 2, and 3, it displays the channel three camera on all.

To make matters more confusing, I tried some different modprobe lines and rebooted. The card has moved to video1 from video0 now.

Solved!!

I had to use some creativity in my google search (used pv143 haupage 1600 to find it) and came accross this zoneminder forum post ->http://www.zoneminder.com/forums/viewtopic.php?t=14796 .

I've been working on this for a week and a half and it figure I find the solution shortly after posting a message.

Thanks for saying what the fix was. I hate when I see a problem and then "nevermind I figured it out", with no info of how it was fixed
